Name
       XtAppAddInput, XtRemoveInput - register and remove an input source

Syntax
       XtInputId XtAppAddInput(app_context, source, condition, proc, client_data)
	  XtAppContext app_context;
	  int source;
	  XtPointer condition;
	  XtInputCallbackProc proc;
	  XtPointer client_data;

       void XtRemoveInput(id)
	  XtInputId id;

Arguments
       app_context
		 Specifies the application context that identifies the application.

       client_data
		 Specifies the argument that is to be passed to the specified procedure when input is available.

       condition Specifies the mask that indicates a read, write, or exception condition or some operating system dependent condition.

       id	 Specifies the ID returned from the corresponding call.

       proc	 Specifies the procedure that is to be called when input is available.

       source	 Specifies the source file descriptor on a UNIX-based system or other operating system dependent device specification.

Description
       The function registers with the Intrinsics read routine a new source of events, which is usually file input but can also be file output.
       Note that file should be loosely interpreted to mean any sink or source of data.  also specifies the conditions under which the source can
       generate events.  When input is pending on this source, the callback procedure is called.

       The legal values for the condition argument are operating-system dependent.  On a UNIX-based system, the condition is some union of and The
       function causes the Intrinsics read routine to stop watching for input from the input source.
