Wake some number of threads waiting on a futex, and move more waiters to another wait queue.
#include <zircon/syscalls.h> zx_status_t zx_futex_requeue_single_owner(const zx_futex_t* value_ptr, zx_futex_t current_value, const zx_futex_t* requeue_ptr, uint32_t requeue_count, zx_handle_t new_requeue_owner);
zx_futex_requeue() for a full description.
zx_futex_requeue_single_owner() returns ZX_OK on success.
ZX_ERR_INVALID_ARGS One of the following is true:
+ Either value_ptr or requeue_ptr is not a valid userspace pointer
+ Either value_ptr or requeue_ptr is not aligned to a
+ value_ptr is the same futex as requeue_ptr
+ new_requeue_owner is currently a member of the waiters for either value_ptr or requeue_ptr
ZX_ERR_BAD_HANDLE new_requeue_owner is not ZX_HANDLE_INVALID, and not a valid handle. ZX_ERR_WRONG_TYPE new_requeue_owner is a valid handle, but is not a handle to a thread. ZX_ERR_BAD_STATE current_value does not match the value at value_ptr.
