Inside a c routine (ie. inside a .c file) is there any way to define a

From xs, it is no problem.
Yes. You can say
SV *var = &PL_sv_undef;
Where should I say it ?
What I want, by using a c routine in a .c file (not .xs) is to return a
value to perl without using RETVAL (I need to return 2 values).
This c routine is defined as extern
In c I would do:
test (&a, &b) ; (in perl I could lie to do something like: test ($a, $b) )
with (in .h):
int test (int*, int*) ;
and in .c:
int test (int* t1, int *t2) {
*t1++ ;
*t2++ ;
return (*t1, *t2) ;
}
This is just a template.
which creates an undefined scalar. But what do you want to do with it?
