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 calendar. 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out of date.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holding outdated information; it merely gives the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.
