_heapadd
Visual Studio .NET 2003
Adds memory to the heap.
int _heapadd( void *memblock, size_t size );
Parameters
- memblock
- Pointer to heap memory.
- size
- Size in bytes of memory to add.
Return Value
If successful, _heapadd returns 0; otherwise, the function returns –1 and sets errno to ENOSYS.
See _doserrno, errno, _sys_errlist, and _sys_nerr for more information on this, and other, return codes.
Remarks
Beginning with Visual C++ version 4.0, the underlying heap structure was moved to the C run-time libraries to support the new debugging features. As a result, _heapadd is no longer supported on any platform that is based on the Win32 API.
