       void XtRemoveInput(id)
	     XtInputId id;

ARGUMENTS
       app_context
		 Specifies the application context that identifies the appli‐
		 cation.

       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.

		 available.

       source	 Specifies the source file descriptor on a UNIX-based system

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 gener‐
       ate events.  When input is pending on this source, the callback proce‐
       dure is called.

       The legal values for the condition argument are operating-system depen‐
       dent.  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.
