Not necessarily. It's up to the implementation whether a plain char is
signed or unsigned.

To compare Unicode strings use wcscmp, prototyped in wchar.h. It's like
strcmp, but it takes two arguments of type wchar_t*, that is, pointer to
wide character.

Hi Everyone,
        I have downloaded a huge text file  (in Chinese) (21Mb)

        I used to use msort to sort big files, which works perfectly
for English Files but not in Chinese.

        This may be due to the strcmp function they used! strcmp
takes two (char *) which is signed. But what I want is strcmp
whichs takes two (unsigned char *)

        Now my question is where can I download a sorting program
which works for UNICODE and can sort EXTREMELY HUGE file? Or where
can I download the source code so that I can make it to unsigned
char!

        Please Help!!!

This doesn't matter here. strcmp() is defined to compare the strings by
interpreting the individual characters as unsigned char values.

The results would be no different if it did.

As someone else pointed out, there is a function (I don't remember the
name) to compare UNICODE chars.  I have a module to sort huge amounts
of data with your own function, look for "bigsort.c" in

  http://www.pci.uni-heidelberg.de/tc/usr/joerg/prg/testbigsort.tar.gz

It should be fairly easy to adapt the required solution from this code.

Hope that helps, Joerg
