Discards the specified global memory block. The lock count of the memory object must be zero.
Note The global functions have greater overhead and provide fewer features than other memory management functions. New applications should use the heap functions unless documentation states that a global function should be used. For more information, see Global and Local Functions.
Syntax
void GlobalDiscard(
[in] h
);
Parameters
[in] h
A handle to the global memory object. This handle is returned by either the GlobalAlloc or GlobalReAlloc function.
Return value
None
Remarks
Although GlobalDiscard discards the object's memory block, the handle to the object remains valid. The process can subsequently pass the handle to the GlobalReAlloc function to allocate another global memory block identified by the same handle.
