In a pthread application, I need to call system() to execute an external program.  When system() is called in a non-main thread, any other calls to system() are blocked until the previous call has returned.  How do we work around the blocking?

But if that IS actually the case, you can always fork/exec yourself. _______________________________________________ Do not post admin requests to the list. They will be ignored.
