NAME        top

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

LIBRARY        top

       POSIX threads library (libpthread,-lpthread)

SYNOPSIS        top

#include <pthread.h>int pthread_attr_setdetachstate(pthread_attr_t *attr, intdetachstate);int pthread_attr_getdetachstate(const pthread_attr_t *attr,int *detachstate);

DESCRIPTION        top

       Thepthread_attr_setdetachstate() function sets the detach state       attribute of the thread attributes object referred to byattr to       the value specified indetachstate.  The detach state attribute       determines whether a thread created using the thread attributes       objectattr will be created in a joinable or a detached state.       The following values may be specified indetachstate:PTHREAD_CREATE_DETACHED              Threads that are created usingattr will be created in a              detached state.PTHREAD_CREATE_JOINABLE              Threads that are created usingattr will be created in a              joinable state.       The default setting of the detach state attribute in a newly       initialized thread attributes object isPTHREAD_CREATE_JOINABLE.       Thepthread_attr_getdetachstate() returns the detach state       attribute of the thread attributes objectattr in the buffer       pointed to bydetachstate.

RETURN VALUE        top

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

ERRORS        top

pthread_attr_setdetachstate() can fail with the following error:EINVALAn invalid value was specified indetachstate.

HISTORY        top

NOTES        top

       Seepthread_create(3) for more details on detached and joinable       threads.       A thread that is created in a joinable state should eventually       either be joined usingpthread_join(3) or detached usingpthread_detach(3); seepthread_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 topthread_detach(3)       orpthread_join(3).

EXAMPLES        top

       Seepthread_attr_init(3).
