— A clipboard function that registers a
int XmClipboardRegisterFormat ( display, format_name, format_length)
Display * display;
char * format_name;
registers a new format. Each format stored on
the clipboard should have a length associated with it; this length must be
known to the clipboard routines. Formats are known as targets in the
Inter-Client Communication Conventions Manual
(ICCCM). All of the
formats specified by version 1.1 of the ICCCM conventions are preregistered.
Any other format that the application wants to use must either be 8-bit data
or be registered via this routine. Failure to register the length of the data
results in incompatible applications across platforms having different
- Specifies a pointer to the Display structure that was returned in a
previous call to XOpenDisplay or XtDisplay.
- Specifies the string name for the new format (target).
- Specifies the format length in bits (8, 16, or 32).
- The format_name must not be NULL, and the format_length must
be 8, 16, or 32.
- The function was successful.
- 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 function failed because the specified format was already registered
with a different length from that specified now. If a specified format was
already registered with the same length as that specified now,
XmClipboardSuccess is returned.
