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(const 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, POSIX.1-2008.

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).
