[libosinfo PATCH 3/6] media: Add create_from_location_with_flags* APIs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The newly added APIs are introduced in order to extend the current
create_from_location* APIs in a way that a flag can be passed in order
to decided whether a media should be created even if the media is not
recognised as bootable by libosinfo.
