System call module questions.

Question

Hello,
I am trying to create a system call module for solaris 2.6 (sparc).
I am trying to avoid useing the /etc/name_to_sysnum file because I dont want my system calls to be dependant on a userland file. What I have done is this.
static struct modlmisc modlmisc = {
&mod_miscops,
"Einstien system call driver"
static struct modlinkage modlinkage = {
MODREV_1,
&modlmisc,
NULL
int
_init(void)
int error;
if ((error = mod_install(&modlinkage)) < 0)
return error;
sysent[SYS_secctl].sy_narg = 6;
sysent[SYS_secctl].sy_callc = (longlong_t (*)()) test;
sysent[SYS_secctl].sy_flags = SE_LOADED | SE_NOUNLOAD | SE_ARGC;
     return 0;
And this works, the only side effect is that my system calls do not have return values. Is there something else that I need to do (without makeing a specfic system call driver that depends on /etc/name_to_sysnum) to have correct return values ?

See the Runtime class.

Also see the "gotchas" of using that class.
