Return Value

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

Remarks

The _heapmin function minimizes the heap by releasing unused heap memory to the operating system.

Note In 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, the only Win32 platform that is supported by _heapmin is Windows NT. The function returns –1 and sets errno to ENOSYS, when it is called by any other Win32 platform.
