Reads the contents of the Windows clipboard into a binary buffer.
BinaryClipGet( handle, format )
(i) handle: handle of buffer.
(i) format: format of clipboard data.
(i) bytes-read: returns the number of bytes read from the clipboard.
Note: 0 in the first parameter of BinaryClipGet returns the size of buffer needed for a subsequent BinaryAlloc, but doesn't attempt to place the contents of clipboard into a buffer.
The following is a list of possible clipboard formats. Note that some of them may not be supported, because the clipboard contains a pointer or handle to external data instead of the data itself.
