typedef'ing Function Pointers |
Hey all,
Another creative question: is it possible to do something like this to type
define a pointer to a specific type of function:
typedef bool (*)(std::string::const_iterator,
std::string::const_iterator) ItCompare;
And if so, how? The above example does not work, btw, I'm just wondering if
there is a way.

I solved this one on my own just after asking. For those who want to know,
the syntax is like this:
typedef bool (*ItCompare)(std::string::const_iterator,
std::string::const_iterator);

As with other typedefs for pointers to functions, the new type alias
should be together with the *:
typedef bool (*ItCompare)(std::string::const_iterator,
std::string::const_iterator);

Try
typedef bool (*ItCompare)
(
std::string::const_iterator,
std::string::const_iterator
);
