Hi,
I'm doing a research on how to allow arbiter clients to map bar regions
into their spaces. It seems to me the approach should be:
1.- Make the arbiter implement paging
2.- Expect clients to mmap() the region files the arbiter generates
Sounds that correct for you?
I'm a bit confused with libpager, the reference manual seems to be obsolete:
https://www.gnu.org/software/hurd/doc/hurd_5.html#SEC32
From this document I assumed I should create a pager for each region
file, call page_demuxer from the arbiter's demuxer and implement
callback functions. But it seems pager_demuxer() is not defined anymore
and servers use pager_start_workers() which I'm not sure what's for.
Is there more recent documentation about libpager?
