Struct miow::Overlapped
[−]
[src]
pub struct Overlapped(_);
A wrapper around OVERLAPPED to provide "rustic" accessors and
initializers.
Methods
impl Overlapped[src]
fn zero() -> Overlapped
Creates a new zeroed out instance of an overlapped I/O tracking state.
This is suitable for passing to methods which will then later get notified via an I/O Completion Port.
unsafe fn from_raw<'a>(ptr: *mut OVERLAPPED) -> &'a mut Overlapped
Creates a new Overlapped function pointer from the underlying
OVERLAPPED, wrapping in the "rusty" wrapper for working with
accessors.
Unsafety
This function doesn't validate ptr nor the lifetime of the returned
pointer at all, it's recommended to use this method with extreme
caution.
fn raw(&self) -> *mut OVERLAPPED
Gain access to the raw underlying data
fn set_offset(&mut self, offset: u64)
Sets the offset inside this overlapped structure.
Note that for I/O operations in general this only has meaning for I/O handles that are on a seeking device that supports the concept of an offset.
fn offset(&self) -> u64
Reads the offset inside this overlapped structure.
fn set_event(&mut self, event: HANDLE)
Sets the hEvent field of this structure.
The event specified can be null.
fn event(&self) -> HANDLE
Reads the hEvent field of this structure, may return null.
