LocalDiscard
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 object s 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.
