Re: [Serusers] exec module question

Jiri, I've got a bit more basic a question. In the exec_s3.cfg file in examples, the statement: if (!exec_msg('blah blah')) { ...dothis... }; I was going to play around and see what return values get through, but I thought first I'd look at the source code: exec.c in modules/exec will return: -1 if execution / pipe error -1 if the execution works but returns a non-zero value 1 if the execution worked and returned a 0 My yacc is a bit rusty. My question is this. I would expect exec_msg() to return a 0 or a non-zero, but my examination of the exec.c file indicates it can't return a zero. That doesn't seem right, am I reading it wrong? It seems to me that the expression !exec_msg() can never evaluate to true, because exec_msg() can't return a 0. ---greg Jiri Kuthan wrote:
