PTHREAD_ATTR_SETDETACHSTATE(3) Library Functions Manual PTHREAD_ATTR_SETDETACHSTATE(3)

NAME

pthread_attr_setdetachstate, pthread_attr_getdetachstateset 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 detached 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() functions, 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].

pthread_attr_setdetachstate() and pthread_attr_getdetachstate() conform to ISO/IEC 9945-1 ANSI/IEEE (“POSIX”) Std 1003.1 Second Edition 1996-07-12.
