LocalFlags info  Overview  Group

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 or LocalReAlloc function.

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

Description
