I'm slightly confused. The locale could be "C" or "POSIX"; otherwise,
can't you just look at its first two characters, which will be the
standard language code?

POSIX is not C.
Does a programming interface exist in the C standard function library that
returns informations in ISO 639 data format from a locale? http://en.wikipedia.org/wiki/ISO_639
Is the API situation any better in desktop environments like GNOME and KDE?

I think POSIX leaves it implementation-defined, except for insisting on
the existence of "POSIX" as the default locale, "C" as a synonymn for
"POSIX", and "" for an implementation-defined "native locale". Cf.
<http://www.opengroup.org/onlinepubs/000095399/utilities/locale.html>
and
<http://www.opengroup.org/onlinepubs/009695399/functions/setlocale.html>
Here's what the manpage for glibc's setlocale has to say about it:
A locale name is typically of the form language[_territory][.code‐
set][@modifier], where language is an ISO 639 language code, territory
is an ISO 3166 country code, and codeset is a character set or encoding
identifier like ISO-8859-1 or UTF-8.
I don't know of an implementation with a different convention, but the
language lawyers in this group could probably dredge up some mainframe
from the 80s that does something different.

I do not like the consequences from this software design aspect that the data
format is implementation-defined. I do not see that the C standard function
library supports a direct mapping from a locale identifier to more language
informations like ISO codes.
I have got the impression that only external libraries from the approach
"International Components for Unicode" can provide the requested functionality
for the C/C++ programming language so far. http://www.icu-project.org/apiref/icu4c/

Well, ish. But I saw nothing atopical about your original question. There
*is* a limit (although the group sports a small number of trolls who
appear to think otherwise), but I don't think you broke it...

You might get a more useful answer here in the next day or two, but on the

There is a group comp.std.c specifically for discussing the standard
itself, as to how to programming in standard C. That group has more
people who are involved in the standardisation process than this group
so you are more likely to get an accurate answer as to whether the
standard might change over there. Be aware though that changes to the C
standard tend to take a long time to be implemented across the board, as
evidence the version released in 1999 is *still* not fully implemented
by most compilers.

This is a lie. They document the opinion of *one individual* about
what's topical on clc.
I guess that it is on-topic to discuss open issues in the standard C
library.
Of course it is, as should be obvious to anyone with an ounce of common
sense.
Those who strut around pretending it's off-topic are never going to help
you anyway, so just ignore them and leave them to wallow in their
absurdities.

Would any software developer like to integrate the capability to query more
language informations like ISO 639 codes into locale programming interfaces by
the standard C library?
Can an extension like a symbol "_NL_IDENTIFICATION_LANGUAGE" for the function
"nl_langinfo" become part of the official API? http://www.gnu.org/software/libc/man...formation.html

Of course it CAN. It won't, because anything of that nature would
make C highly system sensitive. Note that names begining with a
'_' character are generally reserved for the implementation.

IIRC, the current ISO C standard does not require the
implementation to be aware of any external environment variables
for its operation. (That's not to say that a given implementation
cannot use environment variable settings, it's just that ISO C does
not /require/ it.)
So it's not a question of symbol names, but about requiring
certain environment variables to exist in the first place. On some
systems, the very notion of "environment variable" is an unknown
concept.
Also, it's an uphill battle to add X/Open or POSIX functionality to
the ISO C standard library. How would MS/Win32 applications
deal with them, for example, in light of the fact that the Win32
platform already has its own locale functions?
FWIW, I've taken a different approach in my various proposals for
ISO C library enhancements. I borrow the most useful and most
general functionality from several sources (primarily POSIX and
Win32, but also others) and invent an entirely new set of function
and variable names to embody them. That way, no single existing
implementation is favored over the others, but the functionality
still covers all (or most) of them.

Is there a growing demand to complete the standard programming interfaces?
Are more extensions needed for locale data to express personal preferences?
