I am building a python extension dll using C++ and SWIG. I need to return a
character string from a class member function. The problem is the that the
string is not a member of the class, but it is a local string:
char* CFoo::GetName() {
char pc[] = "blah";
.........
return pc;
}
I want to be able to call "print pFoo.GetName()" in python and have "blah"
printed. If I define my function just as above, I get garbage printed since
the data is local and destroyed when the function exits. I know I can
return a PyObject* using PyString_FromString, but then print on that object
doesn't show the string like I need.
Ideas?
