csa_x_process_updates

csa_x_process_updates(library call)									       csa_x_process_updates(library call)

NAME

       csa_x_process_updates -- invoke a calendar application's calendar event handler

SYNOPSIS

       #include <csa/csa.h>
       void csa_x_process_updates(
       CSA_session_handle cal);

DESCRIPTION

       The  csa_x_process_updates  function  checks  to see if there have been calendar updates that are of interest to the client.  If there have
       been one or more calendar updates, and the client previously registered a callback handler using csa_register_callback(3)  for  updates	of
       this type, the callback function is called by csa_x_process_updates.

       The cal argument specifies a calendar session handle.  The callback function will be invoked only if there have been updates to this calen-
       dar.  If cal is set to NULL, the callback function will be invoked if there have been updates to any logged on calendars.

RETURN VALUE

       The csa_x_process_updates function returns no value.

APPLICATION USAGE

       The csa_x_process_updates function is useful for applications that maintain a dynamic representation of calendar information, such as a GUI
       calendar  display.  Because the calendar server can simultaneously maintain multiple read/write connections for the same calendar, any data
       retrieved by a client should be considered immediately out of date.  To create the appearance of a dynamic display of calendar  data,  such
       an application should call csa_x_process_updates as frequently as necessary from within its main event loop.

       One  way  to  do  this  is  to have a timeout handler call csa_x_process_updates at regular intervals.  The duration of the timer should be
       appropriate for the expected user environment.  This does not eliminate the risk of the client  holding	outdated  information;	it  merely
       gives the application control over how old the information can get.
