UNQUEUE_ME(9)                          Futex API reference                          UNQUEUE_ME(9)



NAME
       unqueue_me - Remove the futex_q from its futex_hash_bucket

SYNOPSIS
       int unqueue_me(struct futex_q * q);

ARGUMENTS
       q
           The futex_q to unqueue

DESCRIPTION
       The q->lock_ptr must not be held by the caller. A call to unqueue_me must be paired with
       exactly one earlier call to queue_me.

RETURN
       1 - if the futex_q was still queued (and we removed unqueued it); 0 - if the futex_q was
       already removed by the waking thread
