LocalSize

The LocalSize function returns the current size, in bytes, of the specified local memory object.

Note  The local functions are slower than other memory management functions and do not provide as many features. Therefore, new applications should use the heap functions.

UINT LocalSize(
  HLOCAL  hMem   // handle to local memory object
);

Parameters

hMem

[in] Handle to the local memory object. This handle is returned by the LocalAlloc, LocalReAlloc, or LocalHandle function.

Return Values

If the function succeeds, the return value is the size, in bytes, of the specified local 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, call the LocalFlags function before calling LocalSize.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Windows 95/98: Requires Windows 95 or later.
  Header: Declared in Winbase.h; include Windows.h.
  Library: Use Kernel32.lib.
