Return Value

If successful, _heapadd returns 0; otherwise, the function returns –1 and sets errno to ENOSYS.

Parameters

memblock

Pointer to heap memory

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 Win32 platform and will immediately return –1 when called from an application of this type.
