PTHREAD_ATTR_SETDETACHSTATE(3)                      Linux Programmer's Manual                     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(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_JOIN-
       ABLE.

       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(3) can fail with the following error:

       EINVAL An invalid value was specified in detachstate.

CONFORMING TO
       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).

EXAMPLE
       See pthread_attr_init(3).
