                display.

                A

                state 
              
                A mask16.
             
              Returns the character associated with the keysym
              and the state. The state is a
              mask16
              bit mask representing the state of the display modifier
              keys and pointer buttons. See
              state-mask-key
              in
              paragrpah
              1.6, Data Types. If the
              keysym does not represent a Common Lisp character, then
              nil is returned. This function was called
              keysym-character in X11R4 and older versions of CLX. 
             
              The state determines the bits attribute of the returned
              character, as follows: 
             
              
                | :control | char-control-bit |  
                | :mod-1 | char-meta-bit |  
                | :mod-2 | char-super-bit |  
                | :mod-3 | char-hyper-bit |  
              
                character 
              
                Type character or null.
