hi hackers, i am new to kernel hacking , i am just trying to play with the networking code. i wrote a system call that will copy the mbuf address from the kernel to user space.. the sys call look like this 355 STD BSD { int sn_rqueue(struct mbuf *m);} and the code in the sn_rqueue syscall look like struct mbuf *x; copyout(x,uap->m;sizeof(x)); and the code in the user program look like struct mbuf *m=NULL; syscall(355,m); and when i tryed to read the ' m ' value it still stays as NULL, may be this question is trivial for u guys..but i was struck at this point... i will be very thankful if somebody can help in this... -prady
