Is there any definitive way that a threaded app can detect which thread library it is using, the older Linux Threads or the newer Native POSIX Thread Library. I have found a few functions, such as pthread_tryjoin_np(), that exist only in NPTL, but that will prevent a program from linking with the Linux Threads library.

Why do not you just use #ifdefs and specify what library to use as a build parameter? Dmitry
