    Test Identification /tset/CAPI.os/ioprim/select/T.select,26
    Specification Base Definitions Issue 6
    Location in Spec http://www.opengroup.org/onlinepubs/000095399/functions/select.html
    Problem Summary When nfds is greater than FD_SETSIZE, a call to select() is expected to
    fail. On our platform,
    it does not.
    Problem Text Our select() is not specifically limited by its implementation details.
    We understand that the
    standard clearly states, based on certain historical assumptions, that
    FD_SETSIZE is a fixed
    limit. To be specific, we don't feel it is usefully restrictive to
    require a static limitation that
    does not help the application. Before providing a variant version of
    select() that enforces this
    restriction, we would like to request some time to challenge this
    restriction further.
    Test Output /tset/CAPI.os/ioprim/select/T.select 26 Failed

    Test Description:
    Base Required Deviance
    EINVAL in errno and return -1 on a call to int select(int nfds,
    fd_set
    *readfds, fd_set *writefds, fd_set *exceptfds, const struct timeval
    *timeout) when nfds is greater than FD_SETSIZE.

    Test Information:
    TEST: Call to select returns -1
    ERROR: select did not fail - returned 0

    Review Resolution Minor System Fault (MSF)
    Review Conclusion A minor system fault is granted.

    This behaviour of select() is thought very unlikely to cause any
    problems for applications. THIS WAIVER WAS CLEARED BY NEW TEST RESULTS 8
