There's TextCat:

http://www.let.rug.nl/vannoord/TextCat/

It looks at n-gram frequencies, and can guess pretty reliably from
even a fairly small amount of text.

TextCat is in Perl.  I don't know if there's a C or C++ implementation
but it isn't a huge piece of code - finding a good technique was the
clever part of it.
