/*** *new.h - declarations and definitions for C++ memory allocation functions * * Copyright (c) 1990-2001, Microsoft Corporation. All rights reserved. * *Purpose: * Contains the declarations for C++ memory allocation functions. * * [Public] * *Revision History: * 03-07-90 WAJ Initial version. * 04-09-91 JCR ANSI keyword conformance * 08-12-91 JCR Renamed new.hxx to new.h * 08-13-91 JCR Better set_new_handler names (ANSI, etc.). * 10-03-91 JCR Added _OS2_IFSTRIP switches for ifstrip'ing purposes * 10-30-91 JCR Changed "nhew" to "hnew" (typo in name!) * 11-13-91 JCR 32-bit version. * 06-03-92 KRS Fix CAVIAR #850: _CALLTYPE1 missing from prototype. * 08-05-92 GJF Function calling type and variable type macros. * 01-21-93 GJF Removed support for C6-386's _cdecl. * 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing * 04-07-93 SKS Add _CRTIMP keyword for CRT DLL model * 10-11-93 GJF Support NT SDK and Cuda builds. * 03-03-94 SKS Add _query_new_handler(), _set/_query_new_mode(). * 03-31-94 GJF Conditionalized typedef of _PNH so multiple * inclusions of new.h will work. * 05-03-94 CFW Add set_new_handler. * 06-03-94 SKS Remove set_new_hander -- it does NOT conform to ANSI * C++ working standard. We may implement it later. * 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers. * 02-14-95 CFW Clean up Mac merge. * 04-10-95 CFW Add set_new_handler stub, fix _INC_NEW. * 04-19-95 CFW Change set_new_handler comments, add placement new. * 05-24-95 CFW Add ANSI new handler. * 06-23-95 CFW ANSI new handler removed from build. * 10-05-95 SKS Add __cdecl to new_handler prototype so that the * cleansed new.h matches the checked-in version. * 12-14-95 JWM Add "#pragma once". * 03-04-96 JWM Replaced by C++ header "new". * 03-04-96 JWM MS-specific restored. * 02-20-97 GJF Cleaned out obsolete support for _CRTAPI* and _NTSDK. * Also, detab-ed. * 04-18-97 JWM Placement operator delete() added. * 04-21-97 JWM Placement operator delete() now #if _MSC_VER >= 1200. * 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. * 03-18-01 PML Define new_handler/set_new_handler compatibly with * definitions in (vs7#194908). * 06-15-01 PML Duplicate defs of std::nothrow_t, std::nothrow from * header (vs7#237394) * ****/ #if _MSC_VER > 1000 /*IFSTRIP=IGN*/ #pragma once #endif #ifndef _INC_NEW #define _INC_NEW #ifdef __cplusplus #ifndef _MSC_EXTENSIONS #include #endif #if !defined(_WIN32) #error ERROR: Only Win32 target supported! #endif #ifndef _CRTBLD /* This version of the header files is NOT for user programs. * It is intended for use when building the C runtimes ONLY. * The version intended for public use will not have this message. */ #error ERROR: Use of C runtime library internal header file. #endif /* _CRTBLD */ /* Protect against #define of new */ #pragma push_macro("new") #undef new #ifndef _INTERNAL_IFSTRIP_ #include #endif /* _INTERNAL_IFSTRIP_ */ #if !defined(_W64) #if !defined(__midl) && (defined(_X86_) || defined(_M_IX86)) && _MSC_VER >= 1300 /*IFSTRIP=IGN*/ #define _W64 __w64 #else #define _W64 #endif #endif /* Define _CRTIMP */ #ifndef _CRTIMP #ifdef CRTDLL #define _CRTIMP __declspec(dllexport) #else /* ndef CRTDLL */ #ifdef _DLL #define _CRTIMP __declspec(dllimport) #else /* ndef _DLL */ #define _CRTIMP #endif /* _DLL */ #endif /* CRTDLL */ #endif /* _CRTIMP */ #ifndef _USE_OLD_STDCPP /* Define _CRTIMP2 */ #ifndef _CRTIMP2 #if defined(CRTDLL2) #define _CRTIMP2 __declspec(dllexport) #else /* ndef CRTDLL2 */ #if defined(_DLL) && !defined(_STATIC_CPPLIB) #define _CRTIMP2 __declspec(dllimport) #else /* ndef _DLL && !STATIC_CPPLIB */ #define _CRTIMP2 #endif /* _DLL && !STATIC_CPPLIB */ #endif /* CRTDLL2 */ #endif /* _CRTIMP2 */ #endif /* _USE_OLD_STDCPP */ /* Define __cdecl for non-Microsoft compilers */ #if ( !defined(_MSC_VER) && !defined(__cdecl) ) #define __cdecl #endif /* types and structures */ #ifndef _SIZE_T_DEFINED #ifdef _WIN64 typedef unsigned __int64 size_t; #else typedef _W64 unsigned int size_t; #endif #define _SIZE_T_DEFINED #endif #ifdef _MSC_EXTENSIONS #ifdef _USE_OLD_STDCPP typedef void (__cdecl * new_handler) (); _CRTIMP new_handler __cdecl set_new_handler(new_handler); #else namespace std { typedef void (__cdecl * new_handler) (); _CRTIMP2 new_handler __cdecl set_new_handler(new_handler) throw(); }; using std::new_handler; using std::set_new_handler; #endif #endif #ifndef __NOTHROW_T_DEFINED #define __NOTHROW_T_DEFINED namespace std { /* placement new tag type to suppress exceptions */ struct nothrow_t {}; /* constant for placement new tag */ extern const nothrow_t nothrow; }; void *__cdecl operator new(size_t, const std::nothrow_t&) throw(); void *__cdecl operator new[](size_t, const std::nothrow_t&) throw(); void __cdecl operator delete(void *, const std::nothrow_t&) throw(); void __cdecl operator delete[](void *, const std::nothrow_t&) throw(); #endif #ifndef __PLACEMENT_NEW_INLINE #define __PLACEMENT_NEW_INLINE inline void *__cdecl operator new(size_t, void *_P) {return (_P); } #if _MSC_VER >= 1200 /*IFSTRIP=IGN*/ inline void __cdecl operator delete(void *, void *) {return; } #endif #endif /* * new mode flag -- when set, makes malloc() behave like new() */ _CRTIMP int __cdecl _query_new_mode( void ); _CRTIMP int __cdecl _set_new_mode( int ); #ifndef _PNH_DEFINED typedef int (__cdecl * _PNH)( size_t ); #define _PNH_DEFINED #endif _CRTIMP _PNH __cdecl _query_new_handler( void ); _CRTIMP _PNH __cdecl _set_new_handler( _PNH ); /* * Microsoft extension: * * _NO_ANSI_NEW_HANDLER de-activates the ANSI new_handler.
