Adds memory to the heap.
int _heapadd(
void *memblock,
size_t size
);
Parameters
memblock
Pointer to the heap memory.size
Size of memory to add, in bytes.
Return Value
If successful, _heapadd returns 0; otherwise, the function returns –1 and sets errno to ENOSYS.
For more information about this and other return codes, see _doserrno, errno, _sys_errlist, and _sys_nerr.
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.
