exif_mnote_data_pentax_identify()

int exif_mnote_data_pentax_identify	(	const ExifData *	ed,
		const ExifEntry *	e
	)

Detect if MakerNote is recognized as one handled by the Pentax module.

Parameters

[in]	ed	image ExifData to identify as as a Pentax type
[in]	e	ExifEntry for EXIF_TAG_MAKER_NOTE, from within ed but duplicated here for convenience

Returns

0 if not recognized, nonzero if recognized. The specific nonzero value returned may identify a subtype unique within this module.
