EINVAL

The detachstate parameter is invalid.

Remarks

The pthread_attr_init function initializes the detached state attribute to PTHREAD_CREATE_JOINABLE.

After the thread is created, a joinable thread can be changed to a detached thread, but a detached thread cannot be modified to become a joinable thread.
