PTHREAD_ATTR_GETDETACHSTATEPOSIX Programmer's MaPTHREAD_ATTR_GETDETACHSTATE(P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

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].
