XSynchronize(3X)                                 XSynchronize(3X)



NAME
     XSynchronize,  XSetAfterFunction  -   enable   and   disable
     synchronization

SYNOPSIS
     int (*XSynchronize (display, onoff))()
     Display *display;
     int onoff;

     int (*XSetAfterFunction (display, proc))()
     Display *display;
     int (*proc)();

DESCRIPTION
     If synchronization is enabled, all Xlib functions that gen-
     erate protocol requests call an ``after'' function after
     completing execution.

     The XSynchronize function enables or disables synchroniza-
     tion. If onoff is nonzero, XSychronize enables synchronous
     behavior.  If onoff is 0, XSynchronize disables synchronous
     behavior.

     XSetAfterFunction sets the ``after'' function and returns
     the previous ``after'' function.

   Arguments
     These functions accept the following arguments:

     display Specifies the connection to the X server.

     proc    Specifies the function to be called after an Xlib
             function that generates a protocol request is exe-
             cuted.

     onoff   Specifies whether to enable or disable synchroniza-
             tion.  Possible values are 0 (disable synchroniza-
             tion) or nonzero (enable synchronization).
