NAME

       pthread_attr_setdetachstate,  pthread_attr_getdetachstate  -  set/get  detach  state  attribute in thread
       attributes object

LIBRARY

       POSIX threads library (libpthread, -lpthread)

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);

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.

HISTORY

       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).

EXAMPLES

       See pthread_attr_init(3).
