pthread_attr_setdetachstateLibrary Functions Manpthread_attr_setdetachstate(3)
NAME
pthread_attr_setdetachstate, pthread_attr_getdetachstate - set/get de-
tach 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 attri-
bute 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 de-
tached state.
PTHREAD_CREATE_JOINABLE
Threads that are created using attr will be created in a join-
able state.
The default setting of the detach state attribute in a newly initial-
ized 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 detach-
state.
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.

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).
