PTHREAD_ATTR(3)          BSD Library Functions Manual          PTHREAD_ATTR(3)

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_CRE-ATE_DETACHED PTHREAD_CREATE_DETACHED
     ATE_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 argu-ment argument
     ment 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.

STANDARDS
     pthread_attr_setdetachstate(), pthread_attr_getdetachstate() conform to ISO/IEC 9945-1:1996
     (``POSIX.1'')
