int VT_tracestate (int * state)
Gets logging state of current thread.
Set by configuration options PROCESS/CLUSTER, modified by VT_traceon/off().
There are three states:
0 = thread is logging
1 = thread is currently not logging
2 = logging has been turned off completely
Different threads within one process may be in state 0 and 1 at the same time because VT_traceon/off() sets the state of the calling thread, but not for the whole process.
State 2 is set through the configuration option PROCESS/CLUSTER NO for the whole process and cannot be changed.
