Struct CFFileDescriptor 

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

Safe wrapper around a retained Core Foundation CFFileDescriptor reference.

Implementations

impl CFFileDescriptor

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Adopts a +1 retained CFFileDescriptor pointer and returns None for null.

Safety

A non-null ptr must be a live CFFileDescriptor pointer of the exact dynamic type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

pub unsafe fn from_raw_borrowed(ptr: *mut c_void) -> Option<Self>

Retains a +0 borrowed CFFileDescriptor pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFFileDescriptor pointer of the exact dynamic type for the duration of the retain call.

pub const fn as_ptr(&self) -> *mut c_void

Borrows the raw +0 Core Foundation pointer while self remains alive.

pub fn type_id() -> usize

Returns the Core Foundation type ID for CFFileDescriptor.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFFileDescriptor

pub fn from_raw_fd(native_fd: i32, close_on_invalidate: bool) -> Option<Self>

Wrap a native file descriptor with a no-op callback.

pub fn native_descriptor(&self) -> i32

Underlying native file descriptor.

pub fn invalidate(&self)

Invalidate the descriptor.
