The example above was just something I wrote on the fly, I wasn't missing any semicolons in the code I was working with.
class Child : public Parent
Quote:
This is because we have used the public keyword to define the inheritance relationship on each of the derived classes:
class CRectangle: public CPolygon { ... }
This public keyword after the colon (:) denotes the most accessible level the members inherited from the class that follows it (in this case CPolygon) will have. Since public is the most accessible level, by specifying this keyword the derived class will inherit all the members with the same levels they had in the base class.
If we specify a more restrictive access level like protected, all public members of the base class are inherited as protected in the derived class. Whereas if we specify the most restricting of all access levels: private, all the base class members are inherited as private.

yeah lol custom C++ implementation. how you doing on incorporating the new C++11 features?
if you work with c++ and haven't read Effective C++: 55 Specific Ways to Improve Your Programs and Designs , you probably should (although one of my co-workers suggested that a better subtitle would be '55 specific reasons not to write software in c++').

I'm blissfully unaware of what C++11 is.
Anyway, it turns out the example that I wrote above is over-simplified and it actually works for me - the issue seems to be with overloading virtual functions, which I wasn't doing in the example. I tried compiling this and it gave an error:
Code:
struct StructOne
{
float x;
float y;
};
struct OtherStruct
{
int x;
int y;
};
class Parent
{
public:
virtual ~Parent() {}
virtual int DoStuff( StructOne* x ) { return x->x + x->y; }
virtual int DoStuff( OtherStruct* y ) { return (int)(y->x + y->y); }
};
class Child : public Parent
{
public:
// redefine one function from parent
virtual int DoStuff( OtherStruct* y ) { return (int)(y->x - y->y); }
};
int main( void )
{
StructOne x = { 1, 2 };
Child child;
child.DoStuff( &x );
}

That fixed it for me as well.

sticking this (glob.glob python) into the google led me to an article suggesting glob.iglob is faster on hudge lists of files since it returns an iterator and not an in-memory list: http://everydayscripting.wordpress.c...s-really-cool/
Maybe worth a try! tbh tho I have no idea, I only googled it because I know zero python yet and wondered wtf glob.glob meant

2.3 million files in the worst directory. Using os.dirlist takes about 5 minutes of CPU time to list them. Not near as long the next run so other stuff must have been going on. Will have to see if there is a way to poll the load on the box while the script is running and kill it if the load is too high.
