Hi Eitan,
Thank your for your response.
the ioctl is the example was in Luigi netmap page... maybe Luigi can help
here???????
can you say why the print's are wrong?
They print the addresses of the variables, not their values.
int i = 1234;
printf("i=%d\n", &i); /* Note the &, prints the address of i, or not, at its
whim */
printf("i=%d\n", i); /* Note no &, prints the value of i */
I say "at its whim" because once you have a mismatch between the type
requested (%d requests int) and the type provided (&i provides int *),
you are in the terrain of undefined behaviour, and **ANYTHING** can
happen. Be glad you aren't running on the notoriously twitchy
DeathStation 9000.
