Where does func_id come from?

There's no func_id in the expansion of that macro.

pthread_create() isn't part of the C standard library. As far as this
newsgroup is concerned, it could be anything, and the correct answer to
your question depends upon precisely how pthead_create is declared.
comp.programming.unix would be a more appropriate forum for such a question.

What exactly does "doesn't work" mean? Before you post to
comp.programming.unix, create a simplified version of your program, as
small as possible, which demonstrates the problem. Do a test build and
run to make sure it actually demonstrates the problem. Give them the
exact text of the program that failed. Tell them precisely which
compiler you're using, the command line options you used, and precisely
what error messages, if any, you got when you compiled and linked it. If
"doesn't work" refers to something that happens when you run the
program, after successfully compiling and linking it, then tell them
precisely what input you gave the program, and what precisely the output
was that convinced you that "it doesn't work".
