Hello,
Yes, you was right about VARDATA (working code below, maybe it will help
others), the problem was that I could not find documentation for VARDATA,
maybe you can point to it?
Also, about the
ats = pclose (sendmail);
PG_RETURN_TEXT_P( ats );
Yes, ats is integer, so what is wrong here? actually it is working
normally, or I should know something more?
Code is here:
text *To, *Subject, *Body;
To = PG_GETARG_TEXT_P(0);
char *cTo = (char *) calloc(VARSIZE(To) - VARHDRSZ, sizeof(char));
strncpy(cTo, VARDATA(To), VARSIZE(To)-VARHDRSZ);
and latter:
fprintf (sendmail, "To: %s\n", cTo);
