#include "smtdefn.h"
smtlog_init (void)


Initialises the SMT logging agent. Returns 0 if initialised okay, -1 if there was an error. The logging agent writes data to log files. Create an unnamed thread for each log file you want to manage, then send events to that thread. Supports these public methods:
CYCLE Cycle log file if it already exists.
OPEN Start a new logfile as specified by event body.
APPEND Append to an existing logfile as specified by event body.
PUT Write line to logile, prefixed by date and time.
PLAIN Use plain logfile output (no timestamp).
STAMP Put timestamp at start of each logged line.
CLOSE Close logfile and destroy thread.
Sends errors to the SMTOPER agent; does not send reply events.
