AFAIK that's correct. Although there is an implementation of
comedi_mark_buffer_written(...) in kcomedilib, there are no symbols
exported for it -- and thus it's not usable from the outside.
I _think_ you won't need anything else in addition to that.

_at_comedi devs: Any chance to export such a symbol?
Would it just mean to add

EXPORT_SYMBOL(comedi_mark_buffer_written);

to comedi/kcomedilib/ksyms.c ?

Then it shouldn't be too hard to do it yourself.

Good luck,
