XtAppAddInput(3X11)     COMMAND REFERENCE     XtAppAddInput(3X11)



NAME
     XtAppAddInput, XtRemoveInput - register and remove an input
     source

SYNOPSIS
     XtInputId XtAppAddInput(app_context, source, condition,
     proc, client_data)
           XtAppContext app_context;
           int source;
           caddr_t condition;
           XtInputCallbackProc proc;
           caddr_t client_data;

     void XtRemoveInput(id)
           XtInputId id; This is user-contributed.

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
               XtAppAddInput call.

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

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

DESCRIPTION
     The XtAppAddInput 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.
     XtAppAddInput 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 operating system, the condition
     is some union of XtInputReadMask, XtInputWriteMask, and
     XtInputExceptMask.  The XtRemoveInput function causes the

     input source.
