LocalDiscard info  Overview  Group

The LocalDiscard function discards the specified local memory object. The lock count of the memory object must be zero.

HLOCAL LocalDiscard(

    HLOCAL hlocMem 

// handle of local memory object

   );

Parameters

hlocMem
Identifies the local memory object. This handle is returned by either the LocalAlloc or LocalReAlloc function.

Return Values

If the function succeeds, the return value is the handle of the local memory object.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

LocalDiscard discards only local objects allocated by a process with the LMEM_DISCARDABLE flag. If a process attempts to discard a fixed or locked object, the function fails.

Although LocalDiscard discards the objectís memory block, the handle of the object remains valid. A process can subsequently pass the handle to the LocalReAlloc function to allocate another local memory object identified by the same handle.
