NAME

pthread_attr_setdetachstate, pthread_attr_getdetachstate - set/get detach state attribute in thread attributes object

LIBRARY

POSIX threads library ( libpthread , -lpthread )

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 );

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 .

RETURN VALUE

On success, these functions return 0; on error, they return a nonzero error number.

ERRORS

pthread_attr_setdetachstate () can fail with the following error:

EINVAL

An invalid value was specified in detachstate .

ATTRIBUTES

For an explanation of the terms used in this section, see attributes (7).

STANDARDS

POSIX.1-2008.

HISTORY

POSIX.1-2001.

NOTES

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).

EXAMPLES

See pthread_attr_init (3).
