Just a small issue, the man page for popen/pclose has a small inconsistency about the return value from pclose -- man 3 pclose: > The pclose() function waits for the associated process to terminate and > returns the exit status of the command as returned by wait4(). and then... > The pclose() function returns -1 if stream is not associated with a > ``popened'' command, if stream already ``pclosed'', or if wait4 returns > an error. Actually. I believe neither to be true, it returns (-1) if not opened by popen OR exited with a signal other than EINTR, otherwise the exit status as returned by wait4().
