Re: [suse-programming-e] STL vector as a function parameter with default value (heres another one for you Jerry...)
I've never used that syntax before,
could you explain a little?

I would go with two func signatures.
func() { vector<uint> a; this->func(a); } func(vector<uint> &foo) {...}
But probably there is an even better way.

I think that Davi's solution is relatively portable. In C++, you can have multiple signatures: 1. func() -- Empty parameter list. It simply defines the vector and then calls the other function in the same class. Probably does not need to use this->. 2. func(vector<uint> &foo) -- This is the function that does something with the vector. Because you are calling by reference, I think you must have a vector to reference. Borland may have some non-standard extensions where GCC tends to be a crybaby sometimes.
In this case, your code would probably be more portable. You might also want to make func() inline.
Makes sense once you explain it
I saw the {...} and thought he was using something to do with C++ capabilities to unlimited (not really) number of paramters.
I was thinking too complicatedly.
hehehehe
duh!
simply overloading. sheesh
got it!
don't know that that is any cleaner than just having a global empty vetor except I suppose someone could actually use it or assign some values or something, where with the overload, it couldn't happen.

Think simple. Most programming problems I've faced can be simplified.
good'ol KISS!
