*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 <new> (vs7#194908).
|
|
* 06-15-01 PML Duplicate defs of std::nothrow_t, std::nothrow from
|
|
* header <new> (vs7#237394)
