SMT Version 2.81

smtoper_init

#include "smtdefn.h"
int
smtoper_init (void)

Synopsis

Initialises the SMT operator agent. Returns 0 if initialised okay, -1 if there was an error. The operator agent writes messages to the standard error device. More sophisticated implementations could send messages to consoles. Creates one unnamed thread automatically. Supports these public methods:

ERROR	Handle event as a serious error message.
WARNING	Handle event as a warning message.
INFO	Handle event as an information message.
SET LOG	Send all output to specified thread.
DISABLE	Console ignores all messages.
ENABLE	Console handles messages (default).

Does not send reply events.
