Struct FutexRef 

pub struct FutexRef(/* private fields */);

An owned reference to a Futex.

Implementations

impl FutexRef

pub unsafe fn new(ptr: *mut Futex) -> Self

Takes ownership of the reference.

Safety

The pointer must be a valid Futex.

pub fn ptr(&self) -> *mut Futex

pub fn physical_addr(&self) -> ManagedPhysicalMemoryAddr

pub fn wake(&self, num_wakeups: c_uint) -> c_uint

pub fn listener_count(&self) -> c_uint

pub fn into_c_ptr(self) -> *mut Futex

Ownership of the reference is transferred to the returned pointer.

In otherwords, self is dropped without changing the futex’s refcount, and the returned pointer can be safely used. The refcount should be decremented when the returned pointer is no longer used.
