PTHREAD_ATTR_SETDETACHSTATE(BSD Programmer's ManPTHREAD_ATTR_SETDETACHSTATE(3)NAME
pthread_attr_setdetachstate, pthread_attr_getdetachstate - set and get
detachstate attribute
SYNOPSIS
#include <pthread.h>
int
pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);
int
pthread_attr_getdetachstate(pthread_attr_t *attr, int *detachstate);
DESCRIPTION
The detachstate attribute controls whether the thread is created in a de-
tached state. If the thread is created detached, then use of the ID of
the newly created thread by the pthread_detach(3) or pthread_join(3)
function is an error.
The pthread_attr_setdetachstate() and pthread_attr_getdetachstate() func-
tions, 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
number 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() function will fail if:
[EINVAL] The value of detachstate was not valid.
These functions will not return an error code of [EINTR].
