The LocalFlags function returns information about the specified local memory object.
UINT LocalFlags(
HLOCAL hMem |
// handle of local memory object |
); |
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.
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 |
Description |
LMEM_DISCARDABLE |
The object’s memory block can be discarded. |
LMEM_DISCARDED |
The object’s memory block has been discarded. |
