CMediaType.IsPartiallySpecified method

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() const;

Parameters

This method has no parameters.

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.

Requirements

Header

Mtype.h (include Streams.h)

Library

Strmbase.lib (retail builds);
Strmbasd.lib (debug builds)
