CMediaType::MatchesPartial

The MatchesPartial method determines if this media type matches a partially specified media type.

Syntax

  BOOL MatchesPartial(
    const CMediaType *ppartial
) const;

Parameters

ppartial

Pointer to the media type to match.

Return Value

Returns TRUE if the media types match. Otherwise, returns FALSE.

Remarks

The media type specified by ppartial can have a value of GUID_NULL for the major type, subtype, or format type. Any members with GUID_NULL values are not tested. (In effect, GUID_NULL acts as a wildcard.) Members with values other than GUID_NULL must match for the media type to match.

Requirements

**  Header:** Declared in Mtype.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
