    Problem Summary PG4U.00032 FD_SET, FD_CLR and FD_ISSET macros should be allowed to evaluate their macros more than once.
    Problem Text
    Tests 29,31,33 for sys/time.h fail because they claim that the macros
    FD_SET(), FD_CLR(), and FD_ISSET() should only evaluate their arguments
    once. This requirement is not in CASPEC, and the tests are testing an
    internal implementation detail, which they should not be doing.
    Test Output
    TEST CASE: sys/time.h

    TEST PURPOSE #29
    If the macro void FD_SET(int fd, fd_set *fdset) is
    defined in sys/time.h it shall evaluate each of its
    arguments exactly once, fully protected by parentheses
    where necessary, and return void.
    TEST: Argument evaluation
    ERROR: Argument 1 of FD_SET evaluated 2 times
    29 FAIL

    TEST PURPOSE #31
    If the macro void FD_CLR(int fd, fd_set *fdset) is
    defined in sys/time.h it shall evaluate each of its
    arguments exactly once, fully protected by parentheses
    where necessary, and return void.
    TEST: Argument evaluation
    ERROR: Argument 1 of FD_CLR evaluated 2 times
    31 FAIL

    TEST PURPOSE #33
    If the macro int FD_ISSET(int fd, fd_set *fdset) is
    defined in sys/time.h it shall evaluate each of its
    arguments exactly once, fully protected by parentheses
    where necessary, and return a value of the correct type.
    TEST: Argument evaluation
    ERROR: Argument 1 of FD_ISSET evaluated 2 times
    TEST: Return protection
    TEST: Return type
    33 FAIL

    Review Response
    We recommend this request be refused.

    1170 base resolution #33 has already addressed this issue. It
    states

    REQUEST:

    Traditional implementations of the FD_SET, FD_CLR, FD_ISSET
    macros evaluate their first argument more than once.

    In the absence of further information from the specification the
    test suite assumes that the macros should only evaluate their
    arguments once and flag existing inplementations as being
    non-compliant.

    We belive the specification should be changed to allow existing
    practice.

    X/OPEN RESOLUTION:

    If macro versions of these functions are provided they must
    evaluate their arguments only once. This is an ISO C
    requirement.
