pthread_attr_setdetachstate(3)                        Library Functions Manual

NAME
       pthread_attr_setdetachstate, pthread_attr_getdetachstate - set/get
       detach state attribute in thread attributes object

LIBRARY
       POSIX threads library (libpthread, -lpthread)

SYNOPSIS
       #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 pthread_attr_setdetachstate() function sets the detach state
       attribute of the thread attributes object referred to by attr to the
       value specified in detachstate.  The detach state attribute determines
       whether a thread created using the thread attributes object attr will
       be created in a joinable or a detached state.

       The following values may be specified in detachstate:

       PTHREAD_CREATE_DETACHED
              Threads that are created using attr will be created in a
              detached state.

       PTHREAD_CREATE_JOINABLE
              Threads that are created using attr will be created in a
              joinable state.

       The default setting of the detach state attribute in a newly
       initialized thread attributes object is PTHREAD_CREATE_JOINABLE.

       The pthread_attr_getdetachstate() returns the detach state attribute of
       the thread attributes object attr in the buffer pointed to by
       detachstate.

RETURN VALUE
       On success, these functions return 0; on error, they return a nonzero
       error number.

ERRORS
       pthread_attr_setdetachstate() can fail with the following error:

       EINVAL An invalid value was specified in detachstate.

HISTORY

NOTES
       See pthread_create(3) for more details on detached and joinable
       threads.

       A thread that is created in a joinable state should eventually either
       be joined using pthread_join(3) or detached using pthread_detach(3);
       see pthread_create(3).

       It is an error to specify the thread ID of a thread that was created in
       a detached state in a later call to pthread_detach(3) or
       pthread_join(3).

EXAMPLES
       See pthread_attr_init(3).
