.TH PTHREAD_DETACH 3 LinuxThreads
4
pthread_detach \- put a running thread in the detached state
9
int pthread_detach(pthread_t th);
12
!pthread_detach! put the thread |th| in the detached state. This
13
guarantees that the memory resources consumed by |th| will be freed
14
immediately when |th| terminates. However, this prevents other threads
15
from synchronizing on the termination of |th| using !pthread_join!.
17
A thread can be created initially in the detached state, using the
18
!detachstate! attribute to !pthread_create!(3). In contrast,
19
!pthread_detach! applies to threads created in the joinable state, and
20
which need to be put in the detached state later.
22
After !pthread_detach! completes, subsequent attempts to perform
23
!pthread_join! on |th| will fail. If another thread is already joining
24
the thread |th| at the time !pthread_detach! is called,
25
!pthread_detach! does nothing and leaves |th| in the joinable state.
28
On success, 0 is returned. On error, a non-zero error code is returned.
33
No thread could be found corresponding to that specified by |th|
36
the thread |th| is already in the detached state
