Struct winsafe::IMFGetService

source ·
pub struct IMFGetService(/* private fields */);
Available on crate feature mf only.
Expand description

IMFGetService COM interface over IMFGetServiceVT.

Automatically calls IUnknown::Release when the object goes out of scope.

§Examples

use winsafe::{self as w, prelude::*};

let vmr: w::IBaseFilter; // initialized somewhere

let get_svc = vmr.QueryInterface::<w::IMFGetService>()?;
