Error Message
var : must be a class or namespace when followed by '::'
An unsuccessful attempt was made to form a qualified name.
For example, make sure that your code does not contain a function declaration where the function name begins with ::.
Example
The following sample generates C2825:
// C2825.cpp
typedef int i;
int main() {
int* p = new int;
p->i::i(); // C2825
// try the following line instead
// p->i::~i();
}
