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_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.

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).
