passing a pointer by reference in c++

I have a function that needs to modify a pointer, ex:

bool someFunc(Something* something)
{
   something = somethingElse;
   return true;
}

The pointer is passed by value through and is not modified. How can I modify it?

Thanks

Just change the function signature to look like

bool someFunc(Something* &something)

and you’ll get a modifiable pointer in someFunc().
