NAME 🖥️ pthread_attr_setdetachstate 🖥️

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).

InterfaceAttributeValue

pthread_attr_setdetachstate(), pthread_attr_getdetachstate()

Thread safetyMT-Safe

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).
