_heapadd

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.
