Am I missing > something? yes... that is because FD_SETSIZE was (is it still?) being used as a "multiple" to decide how many bits to allocate/use... to increase the size of FD_SETSIZE simply define it to a new value before you include sys/types.h... then simply limit yourself to the new limit :)... hope this helps... ttyl...
