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 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.

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
