XmClipboardInquireCount returns the number of data item
formats available for the data item in the clipboard. This function also
returns the maximum name-length for all formats in which the data item is
stored.
- display
- Specifies a pointer to the Display structure that was returned in a
previous call to XOpenDisplay or XtDisplay.
- window
- Specifies the window ID of a widget that relates the application window to
the clipboard. The widget's window ID can be obtained through
XtWindow. The same application instance should pass the same window
ID to each of the clipboard functions that it calls.
- count
- Returns the number of data item formats available for the data item in the
clipboard. If no formats are available, this argument equals 0 (zero). The
count includes the formats that were passed by name.
- max_format_name_length
- Specifies the maximum length of all format names for the data item in the
clipboard.
- XmClipboardSuccess
- The function was successful.
- XmClipboardLocked
- The function failed because the clipboard was locked by another
application. The application can continue to call the function again with
the same parameters until the lock goes away. This gives the application
the opportunity to ask if the user wants to keep trying or to give up on
the operation.
- XmClipboardNoData
- The function could not find data on the clipboard corresponding to the
format requested. This could occur because the clipboard is empty; there
is data on the clipboard, but not in the requested format; or the data in
the requested format was passed by name and is no longer available.
