CBaseFilter::QueryVendorInfo

Retrieves a vendor information string.

HRESULT QueryVendorInfo(
  LPWSTR* pVendorInfo
);

Parameters

  • pVendorInfo
    Pointer to a string containing vendor information.

Return Values

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

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 3.0 and later.
