CMediaType::IsPartiallySpecified

The IsPartiallySpecified method determines if the media type is partially defined. A media type is partial if the major type, subtype, or format type is GUID_NULL.

Syntax

BOOL IsPartiallySpecified(void) const;

Return Value

Returns TRUE if the media type is partially specified. Otherwise, returns FALSE.

Remarks

The IPin::Connect method can accept partial media types.

The implementation does not actually test the subtype. If there is a specified format type, the media type is not considered partial, even if the subtype is GUID_NULL.
