Simple thing, but how do I get this */& thing working

Hi,

little help needed here.

I have a function:

Code:

saveData(const vector<MyClass*> &items,const char* filename);

I use const along with & to avoid copy constructor usage.

Now, in the calling program I have a vector:

Code:

vector<MyClass*> items;

...um, how do I call the function?
if I use:

Code:

filecontroller->saveData(items, datafile);

the compiler says:

Code:

passing `const FileController as `this' argument
   of `bool FileController ::saveData(std::vector<MyClass*,
   std::allocator<MyClass*> >&, const char*)' discards qualifiers

How do I call the function correctly?

Regards,

daniel
