On 5 May, Gregory Wood scribbled:
-> I need to read from and write to the dual port memory of a
-> communications card from a program which I would like to run from a
-> normal account (not super user).
->
-> How do I access a specific memory address from a non-super program?
write a kernel device driver moduel that interfaces to that memeory for
you. - they basically is no way - unix is a protected memeory system -
user porcesses have no access to memeory the kernel didnt grant to them
- and it only grants memeory space for devices you have permission to
open (ie mmap()) shared memory or allocated memeory allocated for you
by the kernel.
-> Thanks, Greg Wood.
