HeapFree
The HeapFree function frees a memory block allocated from a heap by the HeapAlloc or HeapReAlloc function.
BOOL HeapFree(
HANDLE hHeap,
| // handle to the heap
| DWORD dwFlags,
| // heap freeing flags
| LPVOID lpMem
| // pointer to the memory to free
| );
|
|
Parameters
hHeap
Specifies the heap whose memory block the function frees. This parameter is a
handle returned by the HeapCreate or GetProcessHeap function.
dwFlags
Specifies several controllable aspects of freeing a memory block. Only one
flag is currently defined; however, all other flag values are reserved for future
use. Specifying this flag will override the corresponding flag specified in the flOptions parameter when the heap was created by using the HeapCreate function:
Flag
| Meaning
| HEAP_NO_SERIALIZE
| Specifies that mutual exclusion will not be used while the function is
accessing the heap. For more information about HEAP_NO_SERIALIZE, see the Remarks for
the HeapCreate function.
|
lpMem
Points to the memory block to free. This pointer is returned by the HeapAlloc or HeapReAlloc function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. An application can call GetLastError for extended error information.
