Sun Java System Web Proxy Server 4.0.11 NSAPI Developer's Guide


The daemon_atrestart function enables you to register a callback function named by 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);




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

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