Dear Standards Board,

    I would like to an request official, binding interpretation
    from WG15 concerning the following point in ISO/IEC
    9945-2:1993 (POSIX.2).

    The interp. request 9945-2-67 (mkdir, Section 4.41) identified wording
    in the standard which was unclear.
    This (almost) identical wording in mkdir also occurs in the description
    for mkfifo.

    Should mkfifo -m mode utilize the current umask in setting permissions?
    Or should the same resolution from interp #67 also apply to mkfifo?

    The 9945-2:1993 rationale for mkfifo says that the -m option was added
    to control the file mode, for consistency with the similar functionality
    provided in the mkdir utility.  Hence, I think that the -m option to
    mkfifo should behave similar to the -m option for mkdir.
    Thank you for your attention to this matter.

    Mark Funkenhauser

Interpretation response

The standard is unclear on this issue, and no conformance distinction can
be made between alternative implementations based on this.  This is being
referred to the sponsor.
