nslog_finalise()

void nslog_finalise

(

void

)

Shut down the logging system.

Shuts down the logging subsystem, resetting to verbose logging and output to stderr. Note, if logging is done after calling this, it will be sent to stderr without filtering.

Obtain a formatted string suitable for prepending to a log message.

Returns

nslog_init()

nserror nslog_init	(	nslog_ensure_t *	ensure,

	)

Initialise the logging system.

Sets up everything required for logging. Processes the argv passed to remove the -v switch for verbose logging. If necessary ensures the output file handle is available.
