int Narc_GetMemberRange	(	const NarcArchive *	narc,
		int	member_id,
		NarcMemberRange *	out_range
	)

Resolves the file offset boundaries of an archived member index.

Parameters

narc	Pointer to initialized archive.
member_id	ID offset of target file.
out_range	Destination container to write boundary coordinates.

Returns

0 on success; negative value if member index is out of bounds.

Narc_Init()

int Narc_Init	(	NarcArchive *	narc,
		const u8 *	data,
		size_t	size
	)

Parameters

narc	Destination structure to populate.
data	Pointer to raw file data.
size	File size in bytes.

Returns

0 on success; negative value on formatting or invalid signature errors.
