PTHREAD_ATTR_SETDETACHSTATE(3)x Programmer's ManualAD_ATTR_SETDETACHSTATE(3)
pthread_attr_setdetachstate, pthread_attr_getdetachstate - set/get detach state attribute in thread attributes object
#include <pthread.h> int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate); int pthread_attr_getdetachstate(const pthread_attr_t *attr, int *detachstate); Compile and link with -pthread.
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.
On success, these functions return 0; on error, they return a nonzero error number.
pthread_attr_setdetachstate() can fail with the following error: EINVAL An invalid value was specified in detachstate.

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_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).
