    Problem Text
    On page 623 of the Systems Interfaces and Headers Issue 4, Version 2
    it states, "Upon successful completion strtol() returns the converted
    value, if any. If no conversion could be performed, 0 is
    returned and errno may be set to [EINVAL]".
    .sp
    Since the word "may" is used, an implementation should not
    have to set errno to EINVAL to be conforming.
    This test should not fail if errno is not set to EINVAL
    when the base is 37.
    Test Output
    strtol(10) with base 37:
    expected: return value 0, errno EINVAL
    or: return value 37
    actual: return value 0, errno 0(NO ERROR)

    Review Information

    Review Type TSMA Review
    Start Date null
    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    According to X/Open resolution VWG/034/111292 there are two separate EINVAL
    conditions for strtol(), one for "no conversion could be performed" and one
    for "the value of base is not supported". The former was omitted from
    the ERRORS section in XSH4 for strtol() but still applies because of the
    description elsewhere in the text. (It was included in the ERRORS section
    for strtoul().)

    Therefore the text quoted by the submitter, "If no conversion could be
    performed, 0 is returned and errno may be set to [EINVAL]", relates to
    the "no conversion" EINVAL error. It does not relate to the "base is not
    supported" EINVAL error, and so this should be treated in the same way as
    other error conditions where the text "may fail" is used without further
    qualification. That is: if the implementation detects the "base is not
    supported" condition, strtol() must return zero and set errno to EINVAL;
    if the implementation does not detect the condition, strtol() must return
    a successful result (or a different error condition). As can be seen
    from the test output, the test allows either of these two behaviours, but
    correctly rejects a return value of zero with errno not set to EINVAL.

    It is recommended that this request be refused.
