Worse, it appears the maximum size of time_t is unrelated to the maximum value accepted by select(2).
Fwiw, I found the following on http://pubs.opengroup.org/onlinepubs/009695399/functions/pselect.html ,---- | Implementations may place limitations on the maximum timeout interval | supported. All implementations shall support a maximum timeout interval | of at least 31 days. If the timeout argument specifies a timeout | interval greater than the implementation-defined maximum value, the | maximum value shall be used as the actual timeout value. Implementations | may also place limitations on the granularity of timeout intervals. If | the requested timeout interval requires a finer granularity than the | implementation supports, the actual timeout interval shall be rounded up | to the next supported value. `---- So I'm a bit surprised you get an EINVAL instead of the timeout being capped to the implementation's max supported value. Was the passed `timeval` structure valid? I.e. is the tv_usec value inside the [0,1e6-1] range? and was tv_sec>=0 ?
