hi,

can someone give me a quick rundown on the steps needed to add a system call?  
the 2 lines included in www.netbsd.org/Documentation/kernel/programming.html 
don't help too much.

i am trying to add a system call, (call it newsyscall() for example)

i've added sys_newsyscall to sys/kern/syscalls.master, ran `make 
init_sysent.c`  i'va also added sys/net/newsys_syscalls.c to sys/conf/files

which function to i define?  newsyscall()  or sys_newsyscall()? (i assume 
sys_newsyscall)

if i want my syscall to verify a uid/gid of the calling process, do i have to 
do anything special to get the proc struct passed to the function?

if anyone can offer pointers, documentation, or examples, i'd appreciate it.
