Granting flex pages in Fiasco.OC / L4Re

[Stefan Kalkowski]

Hi Daniel,

as far as I understood you correctly, you just have to use the
L4_ITEM_MAP_GRANT flag. It will make sure that the entries from the
originator task are revocated, e.g.:

   l4_task_map(dst_task, src_task, snd_fpage,
               cap | L4_ITEM_MAP | L4_MAP_ITEM_GRANT);

I hope this is what you were looking for.

Regards
Stefan
