The pthread_attr_setdetachstate
() function sets
the detach state attribute of the thread attributes object
referred to by attr
to the value specified in detachstate
. The detach state
attribute determines whether a thread created using the
thread attributes object attr
will be created in a
joinable or a detached state.
The following values may be specified in detachstate
:
PTHREAD_CREATE_DETACHED
Threads that are created using attr
will be created in a
detached state.
PTHREAD_CREATE_JOINABLE
Threads that are created using attr
will be created in a
joinable state.
The default setting of the detach state attribute in a
newly initialized thread attributes object is PTHREAD_CREATE_JOINABLE
.
The pthread_attr_getdetachstate
() returns the
detach state attribute of the thread attributes object
attr
in the buffer
pointed to by detachstate
.
pthread_attr_setdetachstate
() can fail with
the following error:
An invalid value was specified in detachstate
.
See pthread_create(3) for more details on detached and joinable threads.
A thread that is created in a joinable state should eventually either be joined using pthread_join(3) or detached using pthread_detach(3); see pthread_create(3).
It is an error to specify the thread ID of a thread that was created in a detached state in a later call to pthread_detach(3) or pthread_join(3).
