PTHREAD_ATTR_SETDETACHSTATELinux Programmer's MaPTHREAD_ATTR_SETDETACHSTATE(3)

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 join-
            able state.
     The default setting of the detach state attribute in a  newly  initial-
     ized 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  detach-
     state.

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).
