+.Sh DESCRIPTION
+The
+.Va 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 
+.Xr pthread_detach 3
+or
+.Xr pthread_join 3
+function is an error.
+.Pp
+The
+.Fn pthread_attr_setdetachstate
+and
+.Fn pthread_attr_getdetachstate
+functions, respectively, set and get the
+.Va detachstate
+attribute in the
+.Fa attr
+object.
+.Pp
+The
+.Fa detachstate
+can be set to either
+.Dv PTHREAD_CREATE_DETACHED
+or
+.Dv PTHREAD_CREATE_JOINABLE .
+A value of
+.Dv PTHREAD_CREATE_DETACHED
+causes
+all threads created with
+.Fa attr
+to be in the detached state, whereas
+using a value of 
+.Dv PTHREAD_CREATE_JOINABLE
+causes all threads created
+with
+.Fa attr
+to be in the joinable state. The default value of the
+.Va detachstate
+attribute is
+.Dv PTHREAD_CREATE_JOINABLE .
+.Pp
+.Sh RETURN VALUE
+Upon successful completion,
+.Fn pthread_attr_setdetachstate
+and
+.Fn pthread_attr_getdetachstate
+return a value of 0. Otherwise, an
+error number is returned to indicate the error.
+.Pp
+The
+.Fn pthread_attr_getdetachstate
+function stores the value of the 
+.Va detachstate
+attribute in 
+.Fa detachstate
+if successful.
+.Sh ERRORS
+The
+.Fn pthread_attr_setdetachstate
+function will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The value of
+.Fa detachstate
+was not valid.
