IMPORT_C TMatchLevel	GetMimeTypeL	(	const TDesC &	aFileName,
			const TDesC8 &	aImageData,
			TDes8 &	aMimeType
		)

Determine whether the supplied data header on its own is recognized, or the data header plus the file suffix together are recognized, and if so return the associated MIME type.

leave: KErrUnderflow Not enough data in descriptor to identify whether it is supported by any plugin.

leave: This method may also leave with one of the system-wide error codes.

Post-condition: If recognized, the caller's descriptor is filled with the MIME types

Parameters

const TDesC & aFileName	The name of the file
const TDesC8 & aImageData	A descriptor containing the header
TDes8 & aMimeType	A user-supplied descriptor in which the MIME type is returned

leave: This method may leave with one of the system-wide error codes.

Post-condition: The caller's array is filled with the supported MIME types

Parameters
