I'm using swig1.3.29 along with tcl8.3. One of the C++ functions that
I've wrapped, is trying to pass back NULL to the tcl script. My tcl
script recognizes the "NULL" as an empty string, as opposed to the
string "NULL" so that I can't check the return value in my script.
Has anyone run into this sort of thing before? How'd you get around it?
