daemon_atrestart

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.

Syntax

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

Returns

void

Parameters

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

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

Example

/* 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);NSAPI_PUBLIC void log_close(void *parameter)
	{system_fclose(global_logfd);}
