       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.

pthread_attr_setdetachstate() can fail with the following error:

       EINVAL An invalid value was specified in detachstate.

       See pthread_attr_init(3).

       attributes object

       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).

       On success, these functions return 0; on error, they return a nonzero error number.
