GlobalSize

The GlobalSize function retrieves the current size, in bytes, of the specified global memory object.

This function is provided only for compatibility with 16-bit versions of Windows.

DWORD GlobalSize(
  HGLOBAL hMem   // handle to the global memory object
);
 

Parameters

hMem

Handle to the global memory object. This handle is returned by either the GlobalAlloc or GlobalReAlloc function.

Return Values

If the function succeeds, the return value is the size, in bytes, of the specified global memory object.

If the specified handle is not valid or if the object has been discarded, the return value is zero. To get extended error information, call GetLastError.

Remarks

The size of a memory block may be larger than the size requested when the memory was allocated.

To verify that the specified object's memory block has not been discarded, use the GlobalFlags function before calling GlobalSize.
