Description
This function is provided for compatibility with X Version 10. To use
it you must include the file <X11/X10.h> and link with the library
-loldX.
Association tables provide a way of storing data locally and accessing
by ID. XLookUpAssoc() retrieves the data stored in an XAssocTable by
its XID. If the matching XID can be found in the table, the routine
returns the data associated with it. If the x_id cannot be found in
the table the routine returns NULL.
For more information on association tables, see Volume One, Appendix B,
X10 Compatibility.
