Anyone have a solution to that? I prefer to not > create a 'c' link That's because $$ is not in your environment but is a builtin in sh, ksh and bash, among other shells. Even the "C" routine I posted cannot get that one for you. However, since $$ is the current process's PID you can build a similar "C" wrapper to return data from getpid(). Sorry no such function exists. Art S. Kagel
