Glibc 2.3 implements both reentrant and a thread local locale APIs. The reentrant API provides versions of isalpha, isupper, toupper, strcoll, and so on that take a separate locale parameter. The thread locale API is simpler - it adds new a uselocale() function, that once called places a thread in its own thread specific local, after which all locale dependent functions use the thread locale instead of the global one (which is the default for backward compatibility).
