Struct winsafe::dshow::IFileSinkFilter

pub struct IFileSinkFilter { /* fields omitted */ }

IFileSinkFilter COM interface over IFileSinkFilterVT. Inherits from IUnknown.

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

Implementations

impl IFileSinkFilter

pub unsafe fn as_ptr(&self) -> *mut *mut IFileSinkFilterVT

Returns the raw pointer to pointer to the COM virtual table.

pub fn QueryInterface<T: ComInterface>(&self) -> WinResult<T>

IUnknown::QueryInterface method.

impl IFileSinkFilter

pub unsafe fn GetCurFile(
    &self,
    mt: Option<&mut AM_MEDIA_TYPE<'_>>
) -> WinResult<String>

IFileSinkFilter::GetCurFile method.

If you pass a AM_MEDIA_TYPE reference to pmt, its pbFormat field may return a valid reference to a format block. If so, you must free it with CoTaskMemFree, or you’ll have a memory leak.

Examples

use winsafe::{CoMemTaskFree, dshow};

let isink: dshow::IFileSinkFilter; // initialized somewhere

let mut ammt = dshow::AM_MEDIA_TYPE::default();
unsafe {
    isink.GetCurFile(Some(&mut ammt))?;
    if let Some(pb_format) = ammt.pbFormat::<dshow::DVINFO>() {
        CoTaskMemFree(pb_format);
    }
}

pub fn SetFileName(
    &self,
    file_name: &str,
    mt: Option<&AM_MEDIA_TYPE<'_>>
) -> WinResult<()>

IFileSinkFilter::SetFileName method.
