Function Documentation

ngcbWatchdogAddCmd()

void ngcbWatchdogAddCmd	(	FILE *	wd,
		const char *	host,
		const char *	cmd )

Add a command to the watchdog instruction list. The command will be executed when the calling process terminates abnormally.

ngcbWatchdogAddProc()

void ngcbWatchdogAddProc	(	FILE *	wd,
		const char *	host,
		int	pid )

Add a process to the watchdog kill-list. When the calling process terminates abnormally the watchdog will kill all processes in the list.

ngcbWatchdogClearCmd()

void ngcbWatchdogClearCmd	(	FILE *	wd,
		const char *	host )

Clear the watchdog instruction list for host. If host is a NULL-pointer then the complete instruction list is cleared.

ngcbWatchdogClearProc()

void ngcbWatchdogClearProc	(	FILE *	wd,
		const char *	host )

Clear the watchdog kill-list for host.

ngcbWatchdogClose()

void ngcbWatchdogClose

(

FILE *

wd

)

Close watchdog connection and terminate the watchdog process. The function returns no value.

ngcbWatchdogDbWrite()

void ngcbWatchdogDbWrite	(	FILE *	wd,
		const char *	host,
		const char *	attr,
		const char *	value )

Add a database attribute update to the watchdog execution list. The attribute will be set to the given value when the calling process terminates abnormally.

ngcbWatchdogOpen()

FILE * ngcbWatchdogOpen	(	int	verbose,
		char *	erms )

Open a watchdog connection. The function returns a stream to be written to. If the verbose flag is greater than zero then the watchdog process is launched in verbose mode in a new terminal.

ngcbWatchdogRemoveCmd()

void ngcbWatchdogRemoveCmd	(	FILE *	wd,
		const char *	host,
		const char *	cmd )

Remove a command from the watchdog instruction list.

ngcbWatchdogRemoveProc()

void ngcbWatchdogRemoveProc	(	FILE *	wd,
		const char *	host,
		int	pid )

Removes a process from the watchdog kill-list. If host is a NULL-pointer then the complete kill-list is cleared.
