.TH PTHREAD_DETACH 3 LinuxThreads
|
|
|
|
.SH NAME
|
|
pthread_detach \- put a running thread in the detached state
|
|
|
|
.SH SYNOPSIS
|
|
#include <pthread.h>
|
|
|
|
int pthread_detach(pthread_t th);
|
|
|
|
.SH 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.
|
|
|
|
.SH "RETURN VALUE"
|
|
On success, 0 is returned. On error, a non-zero error code is returned.
|
|
|
|
.SH ERRORS
|
|

|
|
!ESRCH!
|
|

|
|
.TP
|
|
