How to find the data length of void * type

5954979

I want to get data from the clipboard. The data type returned by GetClipboardData () is void *, how do I know its length?

I only deal with bitmaps, HBITMAP hBitmap = (HBITMAP) GetClipboardData (CF_BITMAP); If you can find the length of hBitmap, you can.

Note that it is the length of the hBitmap, not the data structure, don't tell me it is sizeof (HBITMAP)

BITMAP bm;
GetObject (hBitmap, sizeof (BITMAP),&bm);

HBITMAP is a handle and should be 4 bytes.
