TryGetBaseSetFile()

template<class Tbase_set >

const char* TryGetBaseSetFile	(	const ContentInfo *	ci,
		bool	md5sum,
		const Tbase_set *	s
	)

Check whether there's a base set matching some information.

Parameters

ci	The content info to compare it to.
md5sum	Should the MD5 checksum be tested as well?
s	The list with sets.

Returns

The filename of the first file of the base set, or nullptr if there is no match.
