LocalFlags
The LocalFlags
function returns information about the specified local memory object.
UINT LocalFlags(
HLOCAL hMem |
// handle of local
memory object |
); |
|
Parameters
hMem
Identifies
the local memory object. This handle is returned by either the LocalAlloc
Return Values
If the
function succeeds, the return value is a 32-bit value that specifies the
allocation flags and the lock count for the memory object.
If the
function fails, the return value is the LMEM_INVALID_HANDLE flag, indicating
that the local handle is not valid. To get extended error information, call GetLastError
Remarks
The low-order
byte of the low-order word of the return value contains the lock count of the
object. To retrieve the lock count from the return value, use the
LMEM_LOCKCOUNT mask with the bitwise AND (&) operator. The lock count of
memory objects allocated with the LMEM_FIXED flag is always zero.
The
high-order byte of the low-order word of the return value indicates the
allocation flags of the memory object. It can be zero or any combination of the
following flags:
Value |

LMEM_DISCARDABLE |
