You can find links to drafts of the standard at

c standard - clc-wiki

http://clc-wiki.net/wiki/c_standard

Also a good text book such as K&R2 (see the bibliography of the FAQ at
http://c-faq.com/ )

If you have tried but cannot find the answer then you can ask here and
people will tell you whether a function is a standard C function or not.

Any good, authoritative C reference (such as Kernighan & Ritchie's
"The C Programming Language" or Harbison & Steele's "C: A Reference
Manual" or P.J. Plauger's "The C Standard Library") will contain a
listing of all the C standard library functions; so, if you come
across a library call that isn't described in any of those references,
it's platform-specific.

Uhh... what? You claimed that Microsoft prefixes lower-case symbols
with a '_', and presented tolower as an example. Which is incorrect.

Perhaps your comment would have been clearer if you had used an example
of a lower-case symbol that does fit the pattern you're describing.

Incorrect.

Then please name a lower-case Microsoft specific API, which doesn't have
underscore prefix. Since 'tolower' hasn't, this shows OP by a glance,
that it's a C standard function.

FYI, the default VC++ 6.0 mode, isn't the C conforming mode:

cl /?
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8168 for 80x86
Copyright (C) Microsoft Corp 1984-1998. All rights reserved.

C/C++ COMPILER OPTIONS
....

/Za disable extensions (implies /Op)

This compiles and runs perfectly fine with the default invocation of
MSVC6:
--------
#include <ctype.h>
#include <stdio.h>
>
int main(void)
{
printf("tolower ('a'): %c\n",tolower(' a'));
printf("tolower ('A'): %c\n",tolower(' A'));
>
return 0;
}

So? tolower() isn't a M$ specific function.

I think you misunderstand. In the patois of this NG, the phrase:
"to get compiler in conforming mode" means "cripple your compiler so
that only stricting conforming programs can be compiled". It doesn't
mean anything remotely resembling "enhance your compiler's performance
so that ...".

No, I said *their* lower-case API's. So context here was M$ specific API's.

and presented tolower as an example. Which is incorrect.

Well, it was OP's example. I just tried to tell OP about the M$ naming
conventions relevant for his case.

Perhaps your comment would have been clearer if you had used an example
of a lower-case symbol that does fit the pattern you're describing.

Perhaps, if some non-native speaker of English is unclear, it's better
to ask for a clarification, before jumping to some silly conclusion.

strlwr, strnset, strrev, etc., in <string.h>?

Don't think so, those functions should not available when __STDC__ is
defined.

If you have tried but cannot find the answer then you can ask
here and people will tell you whether a function is a standard
C function or not.

Or just go and get the latest versions at the following:

<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf>
<http://cbfalconer.home .att.net/download/n869_txt.bz2>

N1256 is the latest draft, and up to date. N869 is the last draft
before release of C99, but is a text version and much easier to
use. It is compressed with bzip2.
