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    detachstate    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_CREATE_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].
