Purpose of Logging Client

The logging example shows how a client can log a message by sending a log event to the Event Server. No event loop is required since asynchronous event notification is not needed to accomplish this.

Code

main(
   int argc,
   char **argv
)
{
   /* Initialize the API.
      Application name = "log message"
      No application qualifier.
   */
   SPD_InitClient("log message", NULL);
 
   /* client processing... */
 
   /* Log a message:
      The message "An important..." is written to "logfile"
      as a normal ("NO") message.
      Application name and qualifier are the defaults.
      No time stamp.
   */
   SPD_LogMessage("logfile", "NO",
      "An important event has occurred", NULL, NULL, 0);
 
   /*  more client processing... */
 
   /*  no event loop required if events are only sent,
       but not received.
   */
}
