Hello everyone,


Are there any official site to check whether an API (like tolower or
toLower) is platform specific API (e.g. Microsoft platform specific,
Linux specific) or C common standard API?

The official document is the ISO C standard, which is not free.

However, platform specific API's are usually documented locally by the
implementation, just try to check the MSDN doc or man page.

Good platform-specific documentation will say which standards if any
define a particular function.
If you're reading man pages on a unix-ish system, look for a section
titled 'STANDARDS' or 'CONFORMING TO'. The (somewhat out of date)
version of the Microsoft documentation I use at work has a table in the
description of many non-Win32-specific functions that includes a
"compatibility" column that lists any standards that define the
function.


In the case of Microsoft, their lower-case API's, all have an underscore
prefix, so 'tolower' would be named '_tolower' by M$. Turn on the
compiler switch /Za, to get compiler in conforming mode.

Incorrect.
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;
}
