Draft Status
---------------
Andrew updated the group on the current draft status.
He is awaiting an ISBN number from IEEE before the TC2 document itself
can be published.

Cathy is scheduled to implement the changes to the main document during
the next few weeks.

Andrew reported that IEEE and The Open Group have extended a permissions
grant for the POSIX man pages to another open source project and he is
awaiting signatures before announcing that.

No comments had been received on the draft Change History
or Summary of changes document:

Defect Report Processing
-------------------------
The group picked up on the latest batch of defect reports,
which are available at the following URL:
http://www.opengroup.org/austin/aardvark/latest/

Note: All page and line number references below are for the 2003
edition unless noted otherwise.

XBD ERN 5 ( a large request on the header files section) 
	Accept as marked below

This response is annotated as per the original request.

<sys/mman.h>

(1a) This is a duplicate report XBD ERN 1 which has already been
added as an errata item. No further action is necessary.

(1b) Page 341 (2003 Ed).
Accept, an additional list item "o [MR] |X> Range Memory Locking <X|" 
should be inserted to the list at the start of the DESCRIPTION section
in alphabetical order.

(1c) Page 341 (2003 Ed)
Accept, changed the SYNOPSIS to [MC4] |X> #include <sys/mman.h>
<X| and shaded, where [MC4] is a new short-hand notation for
[MF|SHM|ML|MPR|TYM|SIO|ADV] (or [MF|SHM|ML|MPR|TYM|SIO|ADV|MR].
A related required change for this is to add a new code to the codes
section 1.5.1 of XBD.

<signal.h>

(2a) Page 308, line 10983 (2003 Ed) Change to
"The following shall be declared as functions and may also be
defined as macros. Function prototypes shall be provided." 

<sys/utsname.h>
(2b) Page 373, line 13196 (2003 Ed) Change to:
"The following shall be declared as a function and may also be defined
as a macro. A function prototype shall be provided."

<stdio.h>

(3a) Accept. Page 325, line 11640 (2003 Ed)
Errata item: The function prototype of the function `vsnprintf' misses a
closing bracket.

<sched.h>
(3b) This item only affects the html translation where two end option
markers (<X|) are shown just after the list of function prototypes. 
Only one is needed. Its either a translation error or appears like
that in the source - it should be fixed in errata.


<glob.h>
(4a) Page 238, line 8348 (2003 Ed) Errata, extra white space not needed in
the function prototype for globfree, a space is printed in
between the function name `globfree' and the following opening
bracket. The space should be removed.


<locale.h>
(4b) Page 264, line 9349 (2003 Ed) Errata,
In the list of function prototypes, a space is printed in
between the function name `localeconv' and the following opening
bracket. The space should be removed.

Html help file (note that this is not part of the normative standard
but an addition for useability of the html translation)

(5a) In the section "Codes" of the help file (at least in the
on-line version), an inconsistancy exists between the paragraphs
describing the short-hand notations [MC1] and [MC2], and the
short-hand notation [MC3]. The paragraphs [MC1] and [MC2] end
with "Refer to _Margin_Code_Notation_", followed by "See help on
_Margin_Code_Notation_.", while [MC3] has only the line "Refer
to _Margin_Code_Notation_". Add the line "See help on
_Margin_Code_Notation_." to the paragraph of [MC3].

(5b) Add the new MC4 notation to XBD 1.5.1 Codes, and also to
the html help file. I

 Add after the paragraph describing [MC3]:
 ---start---
 [MC4] |X> Memory Mapped Files, Shared Memory Objects, Process
 Memory Locking, Memory Protection, Typed Memory Objects,
 Synchronized Input and Output, Advisory Information, or Range
 Memory Locking <X|

 The functionality described is optional. The functionality
 described is also an extension to the ISO C standard.

 This is a shorthand notation for combinations of multiple option
 codes.

 Where applicable, functions are marked with the MC4 margin
 legend in the SYNOPSIS section. Where additional semantics apply
 to a function, the material is identified by use of the MC4
 margin legend.

 Refer to _Margin_Code_Notation_.

 /See help on/ _Margin_Code_Notation_.
 ---end---
 and the following paragraph should be added to the section "A
 Feature Dependent on More than Two Options", in the help file,
 after the paragraph describing [MC3]:
 ---start---
 [MC4] |X> The MC4 margin code is shorthand for
 MF|SHM|ML|MPR|TYM|SIO|ADV|MR. Features which are shaded with
 this margin code require support of either the Memory Mapped
 Files, Shared Memory Objects, Process
 Memory Locking, Memory Protection, Typed Memory Objects,
 Synchronized Input and Output, Advisory Information, or Range
 Memory Locking options. <X|
 ---end---

XBD ERN 6 Accept as Marked below

This response is annotated as per the original request.

<sys/select.h>

Page 347 2003 (ed)
Problem [A] 

The layout of the <sys/select.h> header should be reformatted as follows:

 --changes start at p347 line 12338 new layout shown below--
     The <sys/select.h> header shall define the fd_set type as a
 structure.

   The <sys/select.h> header shall define the following macro:

     FD_SETSIZE
         Maximum number of file descriptors in an fd_set structure.

 The following shall be declared as functions,
 defined as macros, or both. If functions are declared, function
 prototypes shall be provided." 

(ed note:code segment)
 void FD_CLR(int fd, fd_set *fdset);
 int FD_ISSET(int fd, fd_set *fdset);
 void FD_SET(int fd, fd_set *fdset);
 void FD_ZERO(fd_set *fdset);
(ed note: end code segment)

     If implemented as macros, these may evaluate their arguments
 more than once, so applications should ensure that the arguments
 they supply are never expressions with side effects.

     The following shall be declared as functions and may also be
 defined as macros. Function prototypes shall be provided.
 --end--

(1a)  No change required

<ucontext.h>
(1b) Page 398 line 14039
Change comma to full stop in:
The following shall be declared as functions and may also be
defined as macros, Function prototypes shall be provided.

(1c) A duplicate request of XBD ERN 5 2(a) and 2(b)

(2a) No Change required

<fmtmsg.h>
(2b) The group felt that the wording is fine
and that no change is required.

<wctype.h>
(2c)  page 426 l 15170
Remove "name" from the end of the sentence:
The <wctype.h> header shall define the following macro name:

<ctype.h>
p214 line 7615 (2003 Ed)
Change
The following are defined as macros:
to
The <ctype.h> header shall define the following as macros:

<arpa/inet.h>
(3a) Page 208 l 7355 (2003 Ed)
Change:
"The following shall either be declared as functions, defined as macros,
or both."
To:
"The following shall be declared as functions, or defined as macros,
or both."

<setjmp.h>
(3b) Page 302 l 10748 (2003 Ed)
Change from:
"The following may be declared as a function, or defined as a macro, or both.
Function prototypes shall be provided."
To:
"The following shall be declared as functions, or defined as macros, or both.
If functions are declared, function prototypes shall
 be provided.".
302 line 10748

(3c) Already fixed in Item A.

XBD ERN 7 BRE nested subpatterns OPEN
The group felt we should leave this open until next time since
discussions are still ongoing on the reflector.

XSH ERN 35 pthread_attr_getstackaddr Accept as Marked as below
                                                                                
Add at the end of DESCRIPTION
                                                                                
If the pthread_attr_getstackaddr() function is called before
the stackaddr attribute has been set the behavior is unspecified.
                                                                                
Add also to pthread_attr_getstack()
                                                                                
If the pthread_attr_getstack() function is called before
the stackaddr attribute has been set the behavior is unspecified.
                                                                                


Any Other Business
------------------

Andrew raised an AOB item, on whether XCU ERN 10 (c99 output files) should
be raised as an interpretation request.It was agreed that it should
be.


Next Steps
-----------
Andrew  will update the aardvark reports with the latest inbound
defect reports.

We still need to discuss what the strategy is post TC2.

There are a number of open action items outstanding:
1. Don Cragun Pathname Resolution proposal
2. Larry Dwyer system() and threads
3. Joerg Schilling wording for XCU ERN 1 pax

The next teleconference call is scheduled for April 8 2004
