Sun Java System Web Server 7.0 Update 4 NSAPI Developer's Guide


daemon_atrestart() Function

The daemon_atrestart function enables to you register a callback function named fn to be used when the server terminates. Use this function when you need a callback function to deallocate resources allocated by an initialization function. The daemon_atrestart function is a generalization of the magnus_atrestart function.

The magnus.conf directives TerminateTimeout and ChildRestartCallback also affect the callback of NSAPI functions.


void daemon_atrestart(void (*fn)(void *), void *data);

Return Values



void (* fn) (void *) is the callback function.

void *data is the parameter passed to the callback function when the server is restarted.


/* Register the log_close function, passing it NULL */ 
/* to close a log file when the server is */
/* restarted or shutdown. */
daemon_atrestart(log_close, NULL);
