BLO_readfile_read_bhead()

std::optional< BHead > BLO_readfile_read_bhead	(	FileReader *	file,
		BHeadType	type,
		bool	do_endian_swap )

Parse the next BHead in the file, increasing the file reader to after the BHead. This automatically converts the stored BHead (one of BHeadType) to the runtime BHead type.

Returns

The next #BHEad or #std::nullopt if the file is exhausted.
