CBaseFilter::QueryVendorInfo (Compact 2013)

3/26/2014

Retrieves a vendor information string.

Syntax

HRESULT QueryVendorInfo(
  LPWSTR* pVendorInfo
);

Parameters

  • pVendorInfo
    Pointer to a string containing vendor information.

Return Value

Returns an HRESULT value (E_NOTIMPL by default).

Remarks

This member function implements the IBaseFilter::QueryVendorInfo method, but only to return E_NOTIMPL.

Filters that want to expose vendor information must override this member function.

If implemented in a derived class, callers should free memory when they are done using it by calling the Win32 CoTaskMemFree function.

Requirements

Header

dshow.h,
Streams.h

Library

ole32.lib,
