/*** *malloc.h - declarations and definitions for memory allocation functions * * Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved. * *Purpose: * Contains the function declarations for memory allocation functions; * also defines manifest constants and types used by the heap routines. * [System V] * * [Public] * *Revision History: * 01-08-87 JMB Standardized header, added heap consistency routines * 02-26-87 BCM added the manifest constant _HEAPBADPTR * 04-13-87 JCR Added size_t and "void *" to declarations * 04-24-87 JCR Added 'defined' statements around _heapinfo * 05-15-87 SKS Cleaned up _CDECL and near/far ptr declarations * corrected #ifdef usage, and added _amblksiz * 12-11-87 JCR Added "_loadds" functionality * 12-18-87 JCR Added _FAR_ to declarations * 02-05-88 JCR Added DLL _amblksiz support * 02-10-88 JCR Cleaned up white space * 04-21-88 WAJ Added _FAR_ to halloc/_fmalloc/_nmalloc * 05-13-88 GJF Added new heap functions * 05-18-88 GJF Removed #defines, added prototypes for _heapchk, _heapset * and _heapwalk * 05-25-88 GJF Added _bheapseg * 08-22-88 GJF Modified to also work for the 386 (small model only, * no far or based heap support) * 12-07-88 JCR DLL refers to _amlbksiz directly now * 01-10-89 JCR Removed sbrk() prototype * 04-28-89 SKS Put parentheses around negative constants * 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage * 08-01-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model) * 10-27-89 JCR Removed near (_n) and _freect/memavl/memmax prototypes * 10-30-89 GJF Fixed copyright * 11-02-89 JCR Changed "DLL" to "_DLL" * 03-01-90 GJF Added #ifndef _INC_MALLOC and #include * stuff. Also, removed some (now) useless preprocessor * directives. * 03-21-90 GJF Replaced _cdecl with _CALLTYPE1 in prototypes. * 04-10-90 GJF Made stackavail() _CALLTYPE1, _amblksiz _VARTYPE1. * 01-17-91 GJF ANSI naming. * 08-20-91 JCR C++ and ANSI naming * 09-23-91 JCR stackavail() not supported in WIN32 * 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now * 01-18-92 JCR put _CRTHEAP_ ifdefs in; this stuff is only needed * for a heap implemented in the runtime (not OS) * 08-05-92 GJF Function calling type and variable type macros. * 08-22-92 SRW Add alloca intrinsic pragma for MIPS * 09-03-92 GJF Merged two changes above. * 09-23-92 SRW Change winheap code to call NT directly always * 01-21-93 GJF Removed support for C6-386's _cdecl. * 02-02-93 SRW Removed bogus semicolon on #pragma * 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing * 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model * Use link-time aliases for old names, not #define's * 04-20-93 SKS _alloca is a compiler intrinsic so alloca must be * #define-d, not aliased as link time using OLDNAMES.LIB. * 09-27-93 GJF Merged NT SDK and Cuda versions. Also, changed the * value of _HEAP_MAXREQ to be more useful (smaller * value to guarantee page-rounding will not overflow). * 10-13-93 GJF Replaced _MIPS_ with _M_MRX000. * 12-13-93 SKS Add _heapused(). * 04-12-94 GJF Special definition for _amblksiz for _DLL. Also, * conditionally include win32s.h for DLL_FOR_WIN32S. * 05-03-94 GJF Made special definition of _amblksiz for _DLL also * conditional on _M_IX86. * 10-02-94 BWT Add PPC support. * 11-03-94 GJF Ensure 8 byte alignment. * 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers. * 02-14-95 CFW Clean up Mac merge. * 05-22-95 GJF Updated _HEAP_MAXREQ. * 05-24-95 CFW Add heap hook. * 12-14-95 JWM Add "#pragma once". * 03-07-96 GJF Added prototypes for small-block heap's get/set * threshold functions. * 02-04-97 GJF Cleaned out obsolete support for Win32s, _CRTAPI* and * _NTSDK. * 08-13-97 GJF Strip __p__amblksiz prototype from release version. * 09-30-97 JWM Restored not-so-obsolete _CRTAPI1 support. * 10-07-97 RDL Added IA64. * 12-15-98 GJF Changes for 64-bit size_t. * 05-13-99 PML Remove _CRTAPI1 * 05-17-99 PML Remove all Macintosh support. * 10-06-99 PML Add _W64 modifier to types which are 32 bits in Win32, * 64 bits in Win64. * 11-08-99 GB Add _aligned_malloc(), _aligned_realloc, _aligned_free() * _aligned_offset_malloc() and _aligned_offset_realloc(). * 12-10-99 GB Add _resetstkoflw(). * 12-16-99 GB Changed HEAP_MAXREQ to 0xFFFFFFFFFFFFFFE0 for Win64 * 01-07-00 GB Fixed macro _mm_free. * 12-08-00 PML Make _resetstkoflw() available to POSIX build. * 04-17-01 PML _resetstkoflw() now returns an int success code. * ****/ #if _MSC_VER > 1000 /*IFSTRIP=IGN*/ #pragma once #endif #ifndef _INC_MALLOC #define _INC_MALLOC #if !defined(_WIN32) #error ERROR: Only Win32 target supported!
