Re: comedi_command kernel space

Use comedi_map() on  init_module() and comedi_unmap() on your
cleanup_module. They are declared in comedilib.h
This way you get a pointer to the buffer. Then use
comedi_get_buffer_offset() and comedi_mark_buffer_read().

Hi, i'm trying to use comedi_get_buffer_offset() and
comedi_mark_buffer_read()
from callback functions with no results. I've seen that there is an example
in
demo directory of comedilib called mmap.c. I'm writing a kernel module so i
cannot use mmap() function isn't it?
How can i solve this problem?
How can i get data from buffer without using mmap() ?
