PTHREAD_DETACH(3) PTHREAD_DETACH(3)
NAME
pthread_detach - put a running thread in the detached
state
SYNOPSIS
#include <pthread.h>
int pthread_detach(pthread_t th);
DESCRIPTION
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 ter-
mination 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.
RETURN VALUE
On success, 0 is returned. On error, a non-zero error code
is returned.
ERRORS
ESRCH No thread could be found corresponding to that
specified by th
EINVAL the thread th is already in the detached state
