Hi,
I have a general question about the POSIX standard of threads (POSIX 1003.1c).
Maybe someone on this mailing list can help.
We are using a vendor pthreads package on a NEC-SX/4 which is called
POSIX-conform. However we have to use a explicit pthread_detach(id), after we
have made a pthread_join(id) in order to release all thread-specific
resources. This detach must be done even on non-detached threads! Therefore a
correct implementation on this machine would be:
pthread_t joe; /* holds pthread thread id */
/* we create a "normal" thread, this means: not detached */
pthread_create(&joe, NULL, fun, arg);
pthread_join(joe, &arg);
pthread_detach(joe); <- this is necessary on NEC! conform?
Is this POSIX-conform or is it a violation of the standard?
Thanks in advance,
Till
