Hi, I am newbie in XS.
Perl code: 
my ($num, $str);
sub_from_xs(\$num, \$str);

XS: 
void
sub_from_xs(SV *num, SV *str)
    INIT:
        if ((!SvROK(num)))
            croak("not a reference");
        
        if ((!SvROK(str)))
            croak("not a reference");
            
        int nx;
        char *sx;
    CODE:
        nx = get_nx();
        sv_setiv_mg(SvRV(num), nx);
        sx = get_sx();
        sv_setpv_mg(SvRV(str), sx);

Is this code correct? How to assign new values to passed references properly?
