Thanks Yoda, I am new to UNIX and did not know about the CODE TAGS. I will make sure to use them on my next questions... However, the code worked, but can you please explain the code...

#include <libexplain/select.h> void explain_select_or_die(int nfds, fd_set *readfds, fd_set *writefds, fd_set *exceptfds, struct timeval *timeout); DESCRIPTION

On failure an explanation will be printed to stderr, obtained from explain_select(3), and then the process terminates by calling exit(EXIT_FAILURE).

Returns: This function only returns on success. On failure, prints an explanation and exits. SEE ALSO
