NAME
       pthread_attr_setdetachstate,  pthread_attr_getdetachstate - set/get de-
       tach 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 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.

CONFORMING TO

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).
