just read perldoc perlcall. Looks like my function will now look like ....
int pushcompout (char * nm, char * val) {
dSP ;
int retval = 0;
ENTER ;
SAVETMPS;
PUSHMARK(SP) ;
if (strlen(nm) > 0 && strlen(val) > 0) {
XPUSHs(sv_2mortal(newSVpv(nm, 0)));
XPUSHs(sv_2mortal(newSVpv(val, 0)));
retval += 2;
}
PUTBACK ;
FREETMPS ;
LEAVE ;
return retval;
}
thanks.
