tttk_Xt_input_handler(3)
CDE
NAME
  tttk_Xt_input_handler - Process ToolTalk events for Xt clients

SYNOPSIS
  #include <Tt/tttk.h>
  void tttk_Xt_input_handler(XtPointer procid,
				  int *source,
				  XtInputId *id);

DESCRIPTION
  If procid is not NULL, tttk_Xt_input_handler passes it to
  tt_default_procid_set(3).  The tttk_Xt_input_handler function then calls
  tt_message_receive(3), which retrieves the next message available, if any,
  for the default procid. If tt_message_receive(3) returns TT_ERR_NOMP, then
  tttk_Xt_input_handler closes the default procid with ttdt_close(3), and
  removes the input source *id with XtRemoveInput(3X) if id is not zero.  If
  a message is available and tt_message_receive(3) returns it (indicating it
  was not consumed by any message or pattern callback), then the ToolTalk
  service passes the message to tttk_message_abandon(3).

RETURN VALUE
  The tttk_Xt_input_handler function returns no value.

APPLICATION USAGE
  The application should use tttk_Xt_input_handler as its Xt input handler
  unless some messages are expected not to be consumed by callbacks. (The
  only messages that absolutely cannot be intercepted and consumed by
  callbacks are those that match observe signatures in a ptype or otype.)

EXAMPLES
       int myTtFd;
       char *myProcID;
       myProcID = ttdt_open(&myTtFd, "WhizzyCalc", "Acme", "1.0", 1);
       /* ... */
       /* Process the message that started us, if any */
       tttk_Xt_input_handler(myProcID, 0, 0);
       /* ... */
       XtAppAddInput(myContext, myTtFd, (XtPointer)XtInputReadMask,
		       tttk_Xt_input_handler, myProcID);
