Имя (Name)
pthread_attr_setdetachstate, pthread_attr_getdetachstate -
set/get detach state attribute in thread attributes object
Синопсис (Synopsis)
#include <pthread.h>
int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);
int pthread_attr_getdetachstate(const pthread_attr_t *attr,
int *detachstate);
Compile and link with -pthread.
Описание (Description)
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.
Возвращаемое значение (Return value)
On success, these functions return 0; on error, they return a
nonzero error number.
Ошибки (Error)
pthread_attr_setdetachstate() can fail with the following error:
EINVAL An invalid value was specified in detachstate.

POSIX.1-2001, POSIX.1-2008.
Примечание (Note)
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).
