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.

Стандарты (Conforming to)

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).
