C and Tk

[Penguin_X]

Hi.

I'm using Tk with Perl. I've take a look on google and many forum about
Tk and C relationship. Is there any way to use it with C ? I would
prefer code compiled Tk programs than interpreted one.

Thank You !

C does not define an interface to any other language in existence. As
far as the C standard is concerned, C is the only language in the
universe.

If you want to interface C to johnny-come-lately languages like Tk,
Perl, C++, Java, or many, many others, you need to use features
provided by either the other language or your operating system. These
are all non-standard extensions as far as C is concerned, and
off-topic here.

Your best bet is asking in a group that supports your particular
compiler/OS combination.

In satifying your statement, would you describe the use of the 'asm'
keyword as not being an interface? Its presence certainly admits that
other languages exist, but it isn't really an *interface*.

A better example is system() where the interface is, in a sense,
completely
specified, even if the execution isn't. ;)

What asm keyword? ANSI/ISO C doesn't have such a keyword.
And the use of the variable name "asm" shouldn't cause syntax
errors, or the compiler is broken.

There is no 'asm' keyword in C. If your implementation provides one,
then it is invading the programmer's namespace. A

Or even johnny-come-early languages like Fortran.

The "asm" keyword was a common extension in some compilers, but it's
not standardized.

Could someone please explain to me, then (honestly), the role of items in
Annex J (informative, Portability issues of the International standard)?
J.5.10 specifically states that 'asm' is a keyword.

Are the items in Annex J "not standard enough" for the purists of
this group?

I fear the answer is "yes"; Annex J is informative, not normative.
It describes in J.5 common extensions but whether this is
__asm, __asm__, asm() or something else is up to the implementation.

It does not matter how you describe asm since it is a non-standard
extension, although a common one.

No, since 'informative' sections are non-normative. So, like footnotes,
they
have no direct bearing on the requirements of a conforming
implementation.

More importantly, a conforming hosted implementation _must_ accept and
correctly execute code like...

#include <stdio.h>

int main(void)
{
int asm = 42;
printf("%d\n", asm);
return 0;
}

There is no such keyword in C. It is merely a common extension,
and not governed by any standard. As such, it does not exist in
this newsgroup.

You're talking to a close minded clique who have ruined comp.lang.c
by trying to moderate unmoderated newsgroup. For some reason they
think "C" is a trademarked term owned by ANSI/ISO; they lack sufficient
neuron mass to realize that "C" actually applies to a variety of
dialects.

Annex J simply provides some background information. It is not normative
which means that its contents do not have any bearing on the language
specification. In fact some of the things it describes, an "asm keyword"
included are in violation of the C standard. When a compiler is run in a
mode that supports it it is not a conforming C implementation because it
breaks the syntax of the language and invades the user namespace. E.g.

int main(void)
{
int asm = 0;
return 0;
}

is a strictly conforming C program with asm having the clear semantics of
a variable identifier.

The explicit purpose (as in "Common Extensions") of section J.5 is to
describe things that are non-standard.
