pthread_attr_getdetachstate(3C) 			   Standard C Library Functions 			   pthread_attr_getdetachstate(3C)

NAME

       pthread_attr_getdetachstate, pthread_attr_setdetachstate - get or set detachstate attribute

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #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  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_setdetachstate() and pthread_attr_getdetachstate(), respectively, set and  get	the  detachstate  attribute  in  the  attr
       object.

       The  detachstate  can be set to either  PTHREAD_CREATE_DETACHED or  PTHREAD_CREATE_JOINABLE. A value of	PTHREAD_CREATE_DETACHED causes all
       threads created with attr to be in the detached state, whereas using a value of PTHREAD_CREATE_JOINABLE causes  all  threads  created  with
       attr to be in the joinable state. The default value of the detachstate attribute is PTHREAD_CREATE_JOINABLE.

RETURN VALUES

       Upon  successful completion, pthread_attr_setdetachstate() and pthread_attr_getdetachstate() return a value of  0. Otherwise, an error num-
       ber is 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() or pthread_attr_getdetachstate() functions may fail if:

       EINVAL	 attr or detachstate is invalid.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

NAME

     pthread_attr_getdetachstate, pthread_attr_setdetachstate -- thread attribute operations

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

     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     One of these thread attributes governs the creation state of the new thread. The new thread can be either created "detached" or "joinable".
     The constants corresponding to these states are PTHREAD_CREATE_DETACHED and PTHREAD_CREATE_JOINABLE respectively.	Creating a "joinable"
     thread allows the user to call pthread_join() and pthread_detach(), with the new thread's ID. A "detached" thread's ID cannot be used with
     pthread_join() and pthread_detach().  The default value for the "detachstate" attribute is PTHREAD_CREATE_JOINABLE.

     The pthread_attr_setdetachstate() function sets the thread's "detachstate" attribute.

     The "detachstate" attribute is set within the attr argument, which can subsequently be used as an argument to pthread_create().

RETURN VALUES

     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.  pthread_attr_getdetachstate(), on
     success, will copy the value of the thread's "detachstate" attribute to the location pointed to by the second function parameter.

ERRORS

     pthread_attr_getdetachstate() will fail if:

     [EINVAL]		Invalid value for attr

     pthread_attr_setdetachstate() will fail if:

     [EINVAL]		Invalid value for attr or detachstate.
