pthread_detach - put a running thread in the detached state
int pthread_detach(pthread_t th);
pthread_detach put the thread th in the detached state. This guarantees
that the memory resources consumed by th will be freed immediately when
th terminates. However, this prevents other threads from synchronizing
on the termination of th using pthread_join.
A thread can be created initially in the detached state, using the
detachstate attribute to pthread_create(3). In contrast,
pthread_detach applies to threads created in the joinable state, and
which need to be put in the detached state later.
After pthread_detach completes, subsequent attempts to perform
pthread_join on th will fail. If another thread is already joining the
thread th at the time pthread_detach is called, pthread_detach does
nothing and leaves th in the joinable state.
On success, 0 is returned. On error, a non-zero error code is returned.
ESRCH No thread could be found corresponding to that specified by th
EINVAL the thread th is already in the detached state
