int
sock_select (int nfds, fd_set *readfds, fd_set *writefds,
             fd_set *errorfds, struct timeval *timeout)

Synopsis

Performs the standard select() call. Use this in preference to select(), as some systems may not be 100% compatible with BSD sockets, Uses the same arguments as the select() call, and gives the same return codes. If sockets are not supported, always returns 0.
