NAME
       pthread_attr_getdetachstate,  pthread_attr_setdetachstate - get and set
       the detachstate attribute

SYNOPSIS
       #include <pthread.h>

       int pthread_attr_getdetachstate(const pthread_attr_t *attr,
              int *detachstate);
       int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);


DESCRIPTION
       The  detachstate  attribute controls whether the thread is created in a
       detached state. If the thread is created detached, then use of  the  ID
       of  the  newly created thread by the pthread_detach() or pthread_join()
       function is an error.

       The  pthread_attr_getdetachstate()  and   pthread_attr_setdetachstate()
       functions, respectively, shall get and set the detachstate attribute in
       the attr object.

       For pthread_attr_getdetachstate(), detachstate shall be set  to  either
       PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.

       For  pthread_attr_setdetachstate(),  the  application shall set detach-
       state to either PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.

       A value of PTHREAD_CREATE_DETACHED shall cause all threads created with
       attr to be in the detached state, whereas using a value of PTHREAD_CRE-
       ATE_JOINABLE shall cause all threads created with attr  to  be  in  the
       joinable state. The default value of the detachstate attribute shall be
       PTHREAD_CREATE_JOINABLE.

RETURN VALUE
       Upon   successful   completion,    pthread_attr_getdetachstate()    and
       pthread_attr_setdetachstate()  shall return a value of 0; otherwise, an
       error number shall be returned to indicate the error.

       The pthread_attr_getdetachstate() function  stores  the  value  of  the
       detachstate attribute in detachstate if successful.

ERRORS
       The pthread_attr_setdetachstate() function shall fail if:

       EINVAL The value of detachstate was not valid


       These functions shall not return an error code of [EINTR].
