I don't see anything special about that code at all. It's just setting up a signal handler, not going about it in any special "safe" way. I think they mean motif-compatible, not 'safe' in any general sense.

I am thinking of moving all the "dirty" stuff to this safe handler function (with dirty i mean everything that's not allowed in a handler function).Do you think that's ok?

Is it safe to do non-signal-safe things in a signal handler? No.

2)What do you think of the traceLog function? Can it be called from the signal handler?

Depends what it does and how it does it.
