Creating Pthreads (Error 22) up vote 0 down vote favorite Learning about pthreads, but I'm having trouble getting them created.

Error 22 from pthread_setspecific appears to mean an invalid key has been supplied. Does pthread_setspecific get called from anywhere inside JNIAST? The stuff in AST that calls pthreads routines reports errors directly to stderr using fprintf. Can output to stderr be retrieved in any pthread_setspecific error 22 way?
