Bug 0000835: file descriptor allocation by pipe() unclear Accepted
http://austingroupbugs.net/view.php?id=835

This item is tagged for TC2-2008

It was noted that in Issue 8, we should move this new section 2.13
closer to section 2.5.

Bug 0000834: definition of file mode Accepted as Marked
http://austingroupbugs.net/view.php?id=834

It was discussed whether this bug duplicates 732, however it was
decided that it is a subset applicable to TC2 as editorial while
732 is a proposal for a new interface in Issue 8.

This item is tagged for TC2-2008

Change XBD 3.168 from

An object containing the file mode bits and file type of a file.

to

An object containing the file mode bits and some information about the file type of a file.

Bug 0000833: SOCK_* flags in getaddrinfo hints->ai_socktype
http://austingroupbugs.net/view.php?id=833

During the call, it was determined that the intent
of 0000411 is that the two new SOCK_ flags are for use only when
opening an fd (socket(), socketpair(), accept4()). An application
can recover the current state of the flags via fcntl() F_GETFL and
F_GETFD - but that state may be different than what was originally
passed in when opening the socket if intervening fcntl() F_SETFL
or F_SETFD have been used. Therefore, the flags should NOT be used
in other interfaces that are referring to a socket type. Thus,
getaddrinfo() should fail with EAI_SOCKTYPE if the caller includes
either flag in the hints, and getsockopt() with SO_TYPE should
return the type with the flags masked out. In the original poster's
description, only the second code snippet is valid.

This item is left open, as we need proposed wording to build upon
requirements added by bug 411.
