NAME

       Ns_SetConnLocationProc, Ns_SetLocationProc - Set the location procedure to use

SYNOPSIS

       #include "ns.h"

       void
       Ns_SetConnLocationProc(Ns_LocationProc *procPtr)

       void
       Ns_SetLocationProc(char *ignored, Ns_LocationProc *procPtr)
_________________________________________________________________

DESCRIPTION

       These  functions  set  the  procedure  to  run  when  a call to Ns_ConnLocation is made. The location is defined in the form METHOD://HOST-
       NAME:PORT, e.g. http://myhost.com:8443.

       Setting the location procedure with these functions will cause all calls to Ns_ConnLocation  to	use  the  location  procedure  you  define
       instead of using the location procedure callback in the communication module for the connection.

       There  may  be  cases  where you want to do this. For example, you could create a location procedure that reports on the values returned by
       communication module location procedure callbacks. At the end of that procedure, you could then return that value after logging the  infor-
       mation making your location procedure is effectively transparent to the server and other modules.

       Ns_SetConnLocationProc(procPtr)

	      Set the function to use when Ns_ConnLocation is called. This function is deprecated. Use Ns_SetLocationProc instead.

       Ns_SetLocationProc(ignored, procPtr)

	      Set the function to use when Ns_ConnLocation is called. The ignored argument is reserved for future use.

NAME

       XAddConnectionWatch - handle Xlib internal connections

SYNTAX

       Status XAddConnectionWatch(display, procedure, client_data)
	     Display *display;
	     XConnectionWatchProc procedure;
	     XPointer client_data;

ARGUMENTS

       display	 Specifies the connection to the X server.

       procedure Specifies the procedure to be called.

       client_data
		 Specifies the additional client data.

DESCRIPTION

       The XAddConnectionWatch function registers a procedure to be called each time Xlib opens or closes an internal connection for the specified
       display.  The procedure is passed the display, the specified client_data, the file descriptor for the connection, a Boolean indicating
       whether the connection is being opened or closed, and a pointer to a location for private watch data.  If opening is True, the procedure
       can store a pointer to private data in the location pointed to by watch_data; when the procedure is later called for this same connection
       and opening is False, the location pointed to by watch_data will hold this same private data pointer.

       This function can be called at any time after a display is opened.  If internal connections already exist, the registered procedure will
       immediately be called for each of them, before XAddConnectionWatch returns.  XAddConnectionWatch returns a nonzero status if the procedure
       is successfully registered; otherwise, it returns zero.

       The registered procedure should not call any Xlib functions.  If the procedure directly or indirectly causes the state of internal connec-
       tions or watch procedures to change, the result is not defined.	If Xlib has been initialized for threads, the procedure is called with the
       display locked and the result of a call by the procedure to any Xlib function that locks the display is not defined unless the executing
       thread has externally locked the display using XLockDisplay.
