Harlinn::Windows::Media::MFMetadata Class Reference

Manages metadata for an object. Metadata is information that describes a media file, stream, or other content. Metadata consists of individual properties, where each property contains a descriptive name and a value. A property may be associated with a particular language. More...

 This function can be used to detect if an object supports a particular COM interface derived from IUnknown.

bool QueryInterface (REFIID riid, void **itf) const
 Queries a COM object for a pointer to one of its interface; identifying the interface by a reference to its interface identifier (IID). If the COM object implements the interface, then it returns a pointer to that interface after calling IUnknown::AddRef on it.

Detailed Description

Manages metadata for an object. Metadata is information that describes a media file, stream, or other content. Metadata consists of individual properties, where each property contains a descriptive name and a value. A property may be associated with a particular language.
