Consumer tools such as gdb or systemtap insert breakpoints on top of the nop, and decode the location operand-strings, like an assembler, to find the values being passed. The operand strings are selected by the compiler for each operand. They are constrained by gcc inline-assembler codes.

You must compile with -std=gnu99 or -std=c99 to use the STAP_PROBE_ASM macro. The STAP_PROBE_ASM macro generates a quoted string to be used in the template portion of the asm statement, concatenated with strings that contain the actual assembly code around the probe site. For example: asm ("before\n" STAP_PROBE_ASM(provider, fooprobe, %eax 4(%esi)) "after"); emits the assembly code for "before\nafter", with a probe in between. The probe arguments are the %eax register, and the value of the memory word located 4 bytes past the address in the %esi register. Note that because this is a simple asm, not a GNU C extended asm statement, these % characters do not need to be doubled to generate literal %reg names. In a GNU C extended asm statement, the probe arguments can be specified using the macro STAP_PROBE_ASM_TEMPLATE(n) for n arguments. The paired macro STAP_PROBE_ASM_OPERANDS gives the C values of these probe arguments, and appears in the input operand list of the asm statement. For example: asm ("someinsn %0,%1\n" // %0 is output operand, %1 is input operand STAP_PROBE_ASM(provider, fooprobe, STAP_PROBE_ASM_TEMPLATE(3)) "otherinsn %[namedarg]" : "r" (outvar) : "g" (some_value), [namedarg] "i" (1234), STAP_PROBE_ASM_OPERANDS(3, some_value, some_ptr->field, 1234)); This is just like writing: STAP_PROBE3(provider, fooprobe, some_value, some_ptr->field, 1234)); but the probe site is right between "someinsn" and "otherinsn". The probe arguments in STAP_PROBE_ASM can be given as assembly operands instead, even inside a GNU C extended asm statement. Note that these can use operand templates like %0 or %[name], and likewise they must write %%reg for a literal operand of %reg. */ #define _SDT_ASM_BODY_1(p,n,...) _SDT_ASM_BODY(p,n,_SDT_ASM_SUBSTR,(__VA_ARGS__)) #define _SDT_ASM_BODY_2(p,n,...) _SDT_ASM_BODY(p,n,/*_SDT_ASM_STRING */,__VA_ARGS__) #define _SDT_ASM_BODY_N2(p,n,no,...) _SDT_ASM_BODY_ ## no(p,n,__VA_ARGS__) #define _SDT_ASM_BODY_N1(p,n,no,...) _SDT_ASM_BODY_N2(p,n,no,__VA_ARGS__) #define _SDT_ASM_BODY_N(p,n,...) _SDT_ASM_BODY_N1(p,n,_SDT_NARG(0, __VA_ARGS__),__VA_ARGS__) #if __STDC_VERSION__ >= 199901L # define STAP_PROBE_ASM(provider, name, ...) \ _SDT_ASM_BODY_N(provider, name, __VA_ARGS__) \ _SDT_ASM_BASE # define STAP_PROBE_ASM_OPERANDS(n, ...) _SDT_ASM_OPERANDS_##n(__VA_ARGS__) #else # define STAP_PROBE_ASM(provider, name, args) \ _SDT_ASM_BODY(provider, name, /* _SDT_ASM_STRING */, (args)) \ _SDT_ASM_BASE #endif #define STAP_PROBE_ASM_TEMPLATE(n) _SDT_ASM_TEMPLATE_##n,"use _SDT_ASM_TEMPLATE_" /* DTrace compatible macro names. */ #define DTRACE_PROBE(provider,probe) \ STAP_PROBE(provider,probe) #define DTRACE_PROBE1(provider,probe,parm1) \ STAP_PROBE1(provider,probe,parm1) #define DTRACE_PROBE2(provider,probe,parm1,parm2) \ STAP_PROBE2(provider,probe,parm1,parm2) #define DTRACE_PROBE3(provider,probe,parm1,parm2,parm3) \ STAP_PROBE3(provider,probe,parm1,parm2,parm3) #define DTRACE_PROBE4(provider,probe,parm1,parm2,parm3,parm4) \ STAP_PROBE4(provider,probe,parm1,parm2,parm3,parm4) #define DTRACE_PROBE5(provider,probe,parm1,parm2,parm3,parm4,parm5) \ STAP_PROBE5(provider,probe,parm1,parm2,parm3,parm4,parm5) #define DTRACE_PROBE6(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6) \ STAP_PROBE6(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6) #define DTRACE_PROBE7(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7) \ STAP_PROBE7(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7) #define DTRACE_PROBE8(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8) \ STAP_PROBE8(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8) #define DTRACE_PROBE9(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9) \ STAP_PROBE9(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9) #define DTRACE_PROBE10(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9,parm10) \ STAP_PROBE10(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9,parm10) #define DTRACE_PROBE11(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9,parm10,parm11) \ STAP_PROBE11(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9,parm10,parm11) #define DTRACE_PROBE12(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9,parm10,parm11,parm12) \ STAP_PROBE12(provider,probe,parm1,parm2,parm3,parm4,parm5,parm6,parm7,parm8,parm9,parm10,parm11,parm12) #endif /* sys/sdt.h */ sys/errno.h 0000644 00000000023 15153117142 0006653 0 ustar 00 #include <errno.h> sys/msg.h 0000644 00000004475 15153117142 0006333 0 ustar 00 /* Copyright (C) 1995-2018 Free Software Foundation, Inc.

Let B be the number of bits in a word, then * (Nb+(B-1))/B words will be used for storage. B - Nb%B bits are * unused. (They are the high-order bits in the highest word.) It * is a class invariant that those unused bits are always zero. * * If you think of %dynamic_bitset as "a simple array of bits," be * aware that your mental picture is reversed: a %dynamic_bitset * behaves the same way as bits in integers do, with the bit at * index 0 in the "least significant / right-hand" position, and * the bit at index Nb-1 in the "most significant / left-hand" * position. Thus, unlike other containers, a %dynamic_bitset's * index "counts from right to left," to put it very loosely. * * This behavior is preserved when translating to and from strings. * For example, the first line of the following program probably * prints "b('a') is 0001100001" on a modern ASCII system. * * @code * #include <dynamic_bitset> * #include <iostream> * #include <sstream> * * using namespace std; * * int main() * { * long a = 'a'; * dynamic_bitset<> b(a); * * cout << "b('a') is " << b << endl; * * ostringstream s; * s << b; * string str = s.str(); * cout << "index 3 in the string is " << str[3] << " but\n" * << "index 3 in the bitset is " << b[3] << endl; * } * @endcode * * Most of the actual code isn't contained in %dynamic_bitset<> * itself, but in the base class __dynamic_bitset_base. The base * class works with whole words, not with individual bits. This * allows us to specialize __dynamic_bitset_base for the important * special case where the %dynamic_bitset is only a single word. * * Extra confusion can result due to the fact that the storage for * __dynamic_bitset_base @e is a vector, and is indexed as such.

Later, B's @c * operator() is called with a single argument @c y. The return * value is the value of @c f(x,y). @c B can be @a called with * various arguments (y1, y2, ...) and will in turn call @c * f(x,y1), @c f(x,y2), ... * * The function @c bind1st is provided to save some typing. It takes the * function and an argument as parameters, and returns an instance of * @c binder1st. * * The type @c binder2nd and its creator function @c bind2nd do the same * thing, but the stored argument is passed as the second parameter instead * of the first, e.g., @c bind2nd(std::minus<float>(),1.3) will create a * functor whose @c operator() accepts a floating-point number, subtracts * 1.3 from it, and returns the result.

Also it has define function int __gthread_active_p () that returns 1 if thread system is active, 0 if not. The threads interface must define the following types: __gthread_key_t __gthread_once_t __gthread_mutex_t __gthread_recursive_mutex_t The threads interface must define the following macros: __GTHREAD_ONCE_INIT to initialize __gthread_once_t __GTHREAD_MUTEX_INIT to initialize __gthread_mutex_t to get a fast non-recursive mutex. __GTHREAD_MUTEX_INIT_FUNCTION to initialize __gthread_mutex_t to get a fast non-recursive mutex. Define this to a function which looks like this: void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *) Some systems can't initialize a mutex without a function call. Don't define __GTHREAD_MUTEX_INIT in this case. __GTHREAD_RECURSIVE_MUTEX_INIT __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION as above, but for a recursive mutex. The threads interface must define the following static functions: int __gthread_once (__gthread_once_t *once, void (*func) ()) int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *)) int __gthread_key_delete (__gthread_key_t key) void *__gthread_getspecific (__gthread_key_t key) int __gthread_setspecific (__gthread_key_t key, const void *ptr) int __gthread_mutex_destroy (__gthread_mutex_t *mutex); int __gthread_recursive_mutex_destroy (__gthread_recursive_mutex_t *mutex); int __gthread_mutex_lock (__gthread_mutex_t *mutex); int __gthread_mutex_trylock (__gthread_mutex_t *mutex); int __gthread_mutex_unlock (__gthread_mutex_t *mutex); int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex); int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex); int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex); The following are supported in POSIX threads only. They are required to fix a deadlock in static initialization inside libsupc++. The header file gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra features are supported.

If the operation is not supported, -1 is returned. If the following are also defined, you should #define __GTHREADS_CXX0X 1 to enable the c++0x thread library.

The function pthread_default_stacksize_np is available in both the archive and shared versions of libpthread. It can be used to determine the default pthread stack size. There is a stub in some shared libc versions which returns a zero size if pthreads are not active. We provide an equivalent stub to handle cases where libc doesn't provide one. */ #if defined(__hppa__) && defined(__hpux__) static volatile int __gthread_active = -1; static inline int __gthread_active_p (void) { /* Avoid reading __gthread_active twice on the main code path. */ int __gthread_active_latest_value = __gthread_active;

Also it has define function int __gthread_active_p () that returns 1 if thread system is active, 0 if not. The threads interface must define the following types: __gthread_key_t __gthread_once_t __gthread_mutex_t __gthread_recursive_mutex_t The threads interface must define the following macros: __GTHREAD_ONCE_INIT to initialize __gthread_once_t __GTHREAD_MUTEX_INIT to initialize __gthread_mutex_t to get a fast non-recursive mutex. __GTHREAD_MUTEX_INIT_FUNCTION to initialize __gthread_mutex_t to get a fast non-recursive mutex. Define this to a function which looks like this: void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *) Some systems can't initialize a mutex without a function call. Don't define __GTHREAD_MUTEX_INIT in this case. __GTHREAD_RECURSIVE_MUTEX_INIT __GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION as above, but for a recursive mutex.

In this case the %sub_match member matched is always true. * The sub_match object stored at index n denotes what matched the marked * sub-expression n within the matched expression. If the sub-expression n * participated in a regular expression match then the %sub_match member * matched evaluates to true, and members first and second denote the range * of characters [first, second) which formed that match. Otherwise matched * is false, and members first and second point to the end of the sequence * that was searched. * * @nosubgrouping */ template<typename _Bi_iter, typename _Alloc = allocator<sub_match<_Bi_iter> > > class match_results : private std::vector<sub_match<_Bi_iter>, _Alloc> { private: /* * The vector base is empty if this does not represent a match (!ready()); * Otherwise if it's a match failure, it contains 3 elements: * [0] unmatched * [1] prefix * [2] suffix * Otherwise it contains n+4 elements where n is the number of marked * sub-expressions: * [0] entire match * [1] 1st marked subexpression * ... * [n] nth marked subexpression * [n+1] unmatched * [n+2] prefix * [n+3] suffix */ typedef std::vector<sub_match<_Bi_iter>, _Alloc> _Base_type; typedef std::iterator_traits<_Bi_iter> __iter_traits; typedef regex_constants::match_flag_type match_flag_type; public: /** * @name 10.?

The %list * class holds (as its only data member) a private list::iterator * pointing to @e D, not to @e A! To get to the head of the %list, * we start at the tail and move forward by one.

This extension turned * out to violate the C++ standard (it can be detected using template * template parameters), and it was removed. * * Here's how a deque<Tp> manages memory. Each deque has 4 members: * * - Tp** _M_map * - size_t _M_map_size * - iterator _M_start, _M_finish * * map_size is at least 8. %map is an array of map_size * pointers-to-@a nodes. (The name %map has nothing to do with the * std::map class, and @b nodes should not be confused with * std::list's usage of @a node.) * * A @a node has no specific type name as such, but it is referred * to as @a node in this file. It is a simple array-of-Tp. If Tp * is very large, there will be one Tp element per node (i.e., an * @a array of one). For non-huge Tp's, node size is inversely * related to Tp size: the larger the Tp, the fewer Tp's will fit * in a node. The goal here is to keep the total size of a node * relatively small and constant over different Tp's, to improve * allocator efficiency. * * Not every pointer in the %map array will point to a node. If * the initial number of elements in the deque is small, the * /middle/ %map pointers will be valid, and the ones at the edges * will be unused. This same situation will arise as the %map * grows: available %map pointers, if any, will be on the ends. As * new nodes are created, only a subset of the %map's pointers need * to be copied @a outward. * * Class invariants: * - For any nonsingular iterator i: * - i.node points to a member of the %map array. (Yes, you read that * correctly: i.node does not actually point to a node.) The member of * the %map array is what actually points to the node. * - i.first == *(i.node) (This points to the node (first Tp element).) * - i.last == i.first + node_size * - i.cur is a pointer in the range [i.first, i.last). NOTE: * the implication of this is that i.cur is always a dereferenceable * pointer, even if i is a past-the-end iterator. * - Start and Finish are always nonsingular iterators. NOTE: this * means that an empty deque must have one node, a deque with <N * elements (where N is the node buffer size) must have one node, a * deque with N through (2N-1) elements must have two nodes, etc. * - For every node other than start.node and finish.node, every * element in the node is an initialized object. If start.node == * finish.node, then [start.cur, finish.cur) are initialized * objects, and the elements outside that range are uninitialized * storage. Otherwise, [start.cur, start.last) and [finish.first, * finish.cur) are initialized objects, and [start.first, start.cur) * and [finish.cur, finish.last) are uninitialized storage. * - [%map, %map + map_size) is a valid, non-empty range. * - [start.node, finish.node] is a valid range contained within * [%map, %map + map_size). * - A pointer in the range [%map, %map + map_size) points to an allocated * node if and only if the pointer is in the range * [start.node, finish.node]. * * Here's the magic: nothing in deque is @b aware of the discontiguous * storage! * * The memory setup and layout occurs in the parent, _Base, and the iterator * class is entirely responsible for @a leaping from one node to the next. * All the implementation routines for deque itself work only through the * start and finish iterators. This keeps the routines simple and sane, * and we can use other standard algorithms as well. */ template<typename _Tp, typename _Alloc = std::allocator<_Tp> > class deque : protected _Deque_base<_Tp, _Alloc> { #ifdef _GLIBCXX_CONCEPT_CHECKS // concept requirements typedef typename _Alloc::value_type _Alloc_value_type;

This design makes it possible to implement something like a * std::forward_list::insert_after on container insertion and * std::forward_list::erase_after on container erase * calls. _M_before_begin is equivalent to * std::forward_list::before_begin. Empty buckets contain * nullptr. Note that one of the non-empty buckets contains * &_M_before_begin which is not a dereferenceable node so the * node pointer in a bucket shall never be dereferenced, only its * next node can be. * * Walking through a bucket's nodes requires a check on the hash code to * see if each node is still in the bucket. Such a design assumes a * quite efficient hash functor and is one of the reasons it is * highly advisable to set __cache_hash_code to true. * * The container iterators are simply built from nodes. This way * incrementing the iterator is perfectly efficient independent of * how many empty buckets there are in the container. * * On insert we compute the element's hash code and use it to find the * bucket index. If the element must be inserted in an empty bucket * we add it at the beginning of the singly linked list and make the * bucket point to _M_before_begin. The bucket that used to point to * _M_before_begin, if any, is updated to point to its new before * begin node. * * On erase, the simple iterator design requires using the hash * functor to get the index of the bucket to update. For this * reason, when __cache_hash_code is set to false the hash functor must * not throw and this is enforced by a static assertion. * * Functionality is implemented by decomposition into base classes, * where the derived _Hashtable class is used in _Map_base, * _Insert, _Rehash_base, and _Equality base classes to access the * "this" pointer. _Hashtable_base is used in the base classes as a * non-recursive, fully-completed-type so that detailed nested type * information, such as iterator type and node type, can be * used. This is similar to the "Curiously Recurring Template * Pattern" (CRTP) technique, but uses a reconstructed, not * explicitly passed, template pattern. * * Base class templates are: * - __detail::_Hashtable_base * - __detail::_Map_base * - __detail::_Insert * - __detail::_Rehash_base * - __detail::_Equality */ template<typename _Key, typename _Value, typename _Alloc, typename _ExtractKey, typename _Equal, typename _H1, typename _H2, typename _Hash, typename _RehashPolicy, typename _Traits> class _Hashtable : public __detail::_Hashtable_base<_Key, _Value, _ExtractKey, _Equal, _H1, _H2, _Hash, _Traits>, public __detail::_Map_base<_Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits>, public __detail::_Insert<_Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits>, public __detail::_Rehash_base<_Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits>, public __detail::_Equality<_Key, _Value, _Alloc, _ExtractKey, _Equal, _H1, _H2, _Hash, _RehashPolicy, _Traits>, private __detail::_Hashtable_alloc< __alloc_rebind<_Alloc, __detail::_Hash_node<_Value, _Traits::__hash_cached::value>>> { static_assert(is_same<typename remove_cv<_Value>::type, _Value>::value, "unordered container must have a non-const, non-volatile value_type");

In practice, the functions are thin * wrappers that dispatch to function templates. Type dependence is * controlled with std::numeric_limits and functions thereof. * * We don't promote @c float to @c double or @c double to <tt>long double</tt> * reflexively. The goal is for @c float functions to operate more quickly, * at the cost of @c float accuracy and possibly a smaller domain of validity. * Similaryly, <tt>long double</tt> should give you more dynamic range * and slightly more pecision than @c double on many systems. * * @section testing Testing * * These functions have been tested against equivalent implementations * from the <a href="http://www.gnu.org/software/gsl"> * Gnu Scientific Library, GSL</a> and * <a href="http://www.boost.org/doc/libs/1_60_0/libs/math/doc/html/index.html>Boost</a> * and the ratio * @f[ * \frac{|f - f_{test}|}{|f_{test}|} * @f] * is generally found to be within 10^-15 for 64-bit double on linux-x86_64 systems * over most of the ranges of validity. * * @todo Provide accuracy comparisons on a per-function basis for a small * number of targets. * * @section bibliography General Bibliography * * @see Abramowitz and Stegun: Handbook of Mathematical Functions, * with Formulas, Graphs, and Mathematical Tables * Edited by Milton Abramowitz and Irene A.

This * reduces code size and protects code parts that have * non-thread-safe side effects. * * Ultimately, forcing parallel execution at compile-time makes * sense. Often, the sequential algorithm implementation is used as * a subroutine, so no reduction in code size can be achieved. Also, * the machine the program is run on might have only one processor * core, so to avoid overhead, the algorithm is executed * sequentially. * * To force sequential execution of an algorithm ultimately at * compile-time, the user must add the tag * gnu_parallel::sequential_tag() to the end of the parameter list, * e. g. * * \code * std::sort(__v.begin(), __v.end(), __gnu_parallel::sequential_tag()); * \endcode * * This is compatible with all overloaded algorithm variants. No * additional code will be instantiated, at all. The same holds for * most algorithm calls with iterators not providing random access. * * If the algorithm call is not forced to be executed sequentially * at compile-time, the decision is made at run-time. * The global variable __gnu_parallel::_Settings::algorithm_strategy * is checked. _It is a tristate variable corresponding to: * * a. force_sequential, meaning the sequential algorithm is executed. * b. force_parallel, meaning the parallel algorithm is executed. * c. heuristic * * For heuristic, the parallel algorithm implementation is called * only if the input size is sufficiently large. For most * algorithms, the input size is the (combined) length of the input * sequence(__s). The threshold can be set by the user, individually * for each algorithm. The according variables are called * gnu_parallel::_Settings::[algorithm]_minimal_n . * * For some of the algorithms, there are even more tuning options, * e. g. the ability to choose from multiple algorithm variants.

Mainly, it lacks iterators.) * * The template argument, @a Nb, may be any non-negative number, * specifying the number of bits (e.g., "0", "12", "1024*1024"). * * In the general unoptimized case, storage is allocated in word-sized * blocks. Let B be the number of bits in a word, then (Nb+(B-1))/B * words will be used for storage. B - Nb%B bits are unused. (They are * the high-order bits in the highest word.) It is a class invariant * that those unused bits are always zero. * * If you think of %bitset as <em>a simple array of bits</em>, be * aware that your mental picture is reversed: a %bitset behaves * the same way as bits in integers do, with the bit at index 0 in * the <em>least significant / right-hand</em> position, and the bit at * index Nb-1 in the <em>most significant / left-hand</em> position. * Thus, unlike other containers, a %bitset's index <em>counts from * right to left</em>, to put it very loosely. * * This behavior is preserved when translating to and from strings. For * example, the first line of the following program probably prints * <em>b('a') is 0001100001</em> on a modern ASCII system. * * @code * #include <bitset> * #include <iostream> * #include <sstream> * * using namespace std; * * int main() * { * long a = 'a'; * bitset<10> b(a); * * cout << "b('a') is " << b << endl; * * ostringstream s; * s << b; * string str = s.str(); * cout << "index 3 in the string is " << str[3] << " but\n" * << "index 3 in the bitset is " << b[3] << endl; * } * @endcode * * Also see: * https://gcc.gnu.org/onlinedocs/libstdc++/manual/ext_containers.html * for a description of extensions. * * Most of the actual code isn't contained in %bitset<> itself, but in the * base class _Base_bitset. The base class works with whole words, not with * individual bits. This allows us to specialize _Base_bitset for the * important special case where the %bitset is only a single word. * * Extra confusion can result due to the fact that the storage for * _Base_bitset @e is a regular array, and is indexed as such.

If a value is set both in the input file and through an environment variable, the environment value takes precedence. */ typedef _GLIBCXX_IMPL_UNORDERED_MAP<std::string, std::string> __env_t; _GLIBCXX_PROFILE_DEFINE_UNINIT_DATA(__env_t, __env);

Operations performed on a sequence alter the values * stored in these pointers, perform reads and writes directly to or * from associated sequences, and alter <em>the stream position</em> and * conversion state as needed to maintain this subsequence relationship. * The three pointers are: * - the <em>beginning pointer</em>, or lowest element address in the * array (called @e xbeg here); * - the <em>next pointer</em>, or next element address that is a * current candidate for reading or writing (called @e xnext here); * - the <em>end pointer</em>, or first element address beyond the * end of the array (called @e xend here). * . * -# The following semantic constraints shall always apply for any set * of three pointers for a sequence, using the pointer names given * immediately above: * - If @e xnext is not a null pointer, then @e xbeg and @e xend shall * also be non-null pointers into the same @c charT array, as * described above; otherwise, @e xbeg and @e xend shall also be null. * - If @e xnext is not a null pointer and @e xnext < @e xend for an * output sequence, then a <em>write position</em> is available. * In this case, @e *xnext shall be assignable as the next element * to write (to put, or to store a character value, into the sequence). * - If @e xnext is not a null pointer and @e xbeg < @e xnext for an * input sequence, then a <em>putback position</em> is available. * In this case, @e xnext[-1] shall have a defined value and is the * next (preceding) element to store a character that is put back * into the input sequence. * - If @e xnext is not a null pointer and @e xnext< @e xend for an * input sequence, then a <em>read position</em> is available. * In this case, @e *xnext shall have a defined value and is the * next element to read (to get, or to obtain a character value, * from the sequence). */ template<typename _CharT, typename _Traits> class basic_streambuf { public: //@{ /** * These are standard types.

This allows pointer cast operations to be * overloaded as necessary by custom pointers. * * Note: The const qualifier works with this pointer adapter as * follows: * * _Tp* == _Pointer_adapter<_Std_pointer_impl<_Tp> >; * const _Tp* == _Pointer_adapter<_Std_pointer_impl<const _Tp> >; * _Tp* const == const _Pointer_adapter<_Std_pointer_impl<_Tp> >; * const _Tp* const == const _Pointer_adapter<_Std_pointer_impl<const _Tp> >; */ template<typename _Storage_policy> class _Pointer_adapter : public _Storage_policy { public: typedef typename _Storage_policy::element_type element_type; // These are needed for iterator_traits typedef std::random_access_iterator_tag iterator_category; typedef typename _Unqualified_type<element_type>::type value_type; typedef std::ptrdiff_t difference_type; typedef _Pointer_adapter pointer; typedef typename _Reference_type<element_type>::reference reference; // Reminder: 'const' methods mean that the method is valid when the // pointer is immutable, and has nothing to do with whether the // 'pointee' is const. // Default Constructor (Convert from element_type*) _Pointer_adapter(element_type* __arg = 0) { _Storage_policy::set(__arg); } // Copy constructor from _Pointer_adapter of same type. _Pointer_adapter(const _Pointer_adapter& __arg) { _Storage_policy::set(__arg.get()); } // Convert from _Up* if conversion to element_type* is valid. template<typename _Up> _Pointer_adapter(_Up* __arg) { _Storage_policy::set(__arg); } // Conversion from another _Pointer_adapter if _Up if static cast is // valid. template<typename _Up> _Pointer_adapter(const _Pointer_adapter<_Up>& __arg) { _Storage_policy::set(__arg.get()); } // Destructor ~_Pointer_adapter() { } // Assignment operator _Pointer_adapter& operator=(const _Pointer_adapter& __arg) { _Storage_policy::set(__arg.get()); return *this; } template<typename _Up> _Pointer_adapter& operator=(const _Pointer_adapter<_Up>& __arg) { _Storage_policy::set(__arg.get()); return *this; } template<typename _Up> _Pointer_adapter& operator=(_Up* __arg) { _Storage_policy::set(__arg); return *this; } // Operator*, returns element_type& inline reference operator*() const { return *(_Storage_policy::get()); } // Operator->, returns element_type* inline element_type* operator->() const { return _Storage_policy::get(); } // Operator[], returns a element_type& to the item at that loc. inline reference operator[](std::ptrdiff_t __index) const { return _Storage_policy::get()[__index]; } // To allow implicit conversion to "bool", for "if (ptr)..." private: typedef element_type*(_Pointer_adapter::*__unspecified_bool_type)() const; public: operator __unspecified_bool_type() const { return _Storage_policy::get() == 0 ? 0 : &_Pointer_adapter::operator->; } // ! operator (for: if (!ptr)...) inline bool operator!() const { return (_Storage_policy::get() == 0); } // Pointer differences inline friend std::ptrdiff_t operator-(const _Pointer_adapter& __lhs, element_type* __rhs) { return (__lhs.get() - __rhs); } inline friend std::ptrdiff_t operator-(element_type* __lhs, const _Pointer_adapter& __rhs) { return (__lhs - __rhs.get()); } template<typename _Up> inline friend std::ptrdiff_t operator-(const _Pointer_adapter& __lhs, _Up* __rhs) { return (__lhs.get() - __rhs); } template<typename _Up> inline friend std::ptrdiff_t operator-(_Up* __lhs, const _Pointer_adapter& __rhs) { return (__lhs - __rhs.get()); } template<typename _Up> inline std::ptrdiff_t operator-(const _Pointer_adapter<_Up>& __rhs) const { return (_Storage_policy::get() - __rhs.get()); } // Pointer math // Note: There is a reason for all this overloading based on different // integer types.
