Hi,
I have the following piece of code,
void goo(int);
void goo(unsigned int);
enum Enum {E1,E2}
void foo ()
{
Enum e = E1;
goo(e); // Is this call ambiguos?
}
The DWP in 4.5 (integral promotion) point 2 says that
"An rvalue of type wchar_t or an enumeration type can be converted to an
rvalue of the _first_ of the following types that can represent all the values
of the source type: int, unsigned int, long, unsigned long."
Does this mean that in the above example the call to goo(e) should be resolved
to goo(int)? or in other words is the promotion enum -> int better than
enum -> unsigned int in this case?
thanks in advance
