*thrownew.cpp - explicit replacement operator new that throws std::bad_alloc
|
|
*
|
|
* Copyright (c) 2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* Provide an explicit operator new that throws std::bad_alloc on
|
|
* memory allocation failure.
|
|
*
|
|
* Link with this object to get ANSI C++ new handler behavior. This is
|
|
* provided for those circumstances where the normal throwing new found
|
|
* in the C++ Standard Library (libcp, libcpmt, or msvcprt.lib) isn't
|
|
* being found by the linker before the legacy non-throwing new in the
|
|
* main C Runtime (libc, libcmt, or msvcrt.lib).
|
|
*
|
|
*
|
|
*Revision History:
|
|
* 06-14-01 PML Module created.
