LocalFlags function

Retrieves information about the specified local memory object.

Note  This function is provided only for compatibility with 16-bit versions of Windows. New applications should use the heap functions. For more information, see Remarks.
 

Syntax

UINT LocalFlags(
  HLOCAL hMem
);

Parameters

hMem

A handle to the local memory object. This handle is returned by either the LocalAlloc or LocalReAlloc function.

Return Value

If the function succeeds, the return value specifies the allocation values and the lock count for the memory object.

If the function fails, the return value is LMEM_INVALID_HANDLE, 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 LMEM_FIXED is always zero.

The high-order byte of the low-order word of the return value indicates the allocation values of the memory object. It can be zero or LMEM_DISCARDABLE.

The local functions have greater overhead and provide fewer features than other memory management functions. New applications should use the heap functions unless documentation states that a local function should be used. For more information, see Global and Local Functions.
