First, the stringPtr work is unnecessary; you can pass an Rb String in

I don't believe that applies in this case; from his description, it
sounds
like the fourth parameter is an output buffer where nc_get_var1_text
can
write its results. If that is the case, then it would be very bad news
to
pass in an RB string; the CString type is equivalent to "const char*",
not
to "char*".
Oops; my eyes put the const in the wrong place. You're quite right.
