PTHREAD_ATTR_SETDETACHSTATE(3)

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

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.

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.

CONFORMING TO
POSIX.1-2001, POSIX.1-2008.

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).

EXAMPLE
See pthread_attr_init(3).
