The GlobalSize function retrieves the current size, in bytes, of the specified global memory object.
DWORD GlobalSize(
HGLOBAL hMem |
// handle to the global memory object |
); |
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.
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.
