XtAppAddInput(3Xt)														XtAppAddInput(3Xt)

NAME
       XtAppAddInput, XtRemoveInput - register and remove an input source

SYNOPSIS
       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
       Specifies  the application context that identifies the application.  Specifies the argument that is to be passed to the specified procedure
       when input is available.  Specifies the mask that indicates a read, write, or exception condition or some operating system dependent condi-
       tion.   Specifies  the  ID  returned from the corresponding XtAppAddInput call.	Specifies the procedure that is to be called when input is
       available.  Specifies the source file descriptor on a UNIX-based 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-based system, the condition is some union of XtInpu-
       tReadMask,  XtInputWriteMask,  and  XtInputExceptMask.  The  XtRemoveInput function causes the Intrinsics read routine to stop watching for
       input from the input source.

BUGS
       In ANSI C it is necessary to cast the condition to an XtPointer, for example:

       XtAppAddInput(app_context, source, (XtPointer) (XtInputReadMask | XtInputWriteMask), proc, client_data);
