Member Data Documentation

child_cleartid_addr

ADDR arion::ARION_THREAD::child_cleartid_addr

The address of the child_tid variable to be cleared when the thread exits (used with CLONE_CHILD_CLEARTID).

child_settid_addr

ADDR arion::ARION_THREAD::child_settid_addr

The address of the child_tid variable to be set when the thread starts (used with CLONE_CHILD_SETTID).
