 Posted: Mon May 21, 2007 5:12 am Post subject: Question about 8.3/10 (function parameter pack) |
 |
|
Hi,
in 8.3/10 of the latest draft (N2289) the example contains:
template<typename... T> void f(T (* ...T)(int, int);
int add(int, int);
float subtract(int, int);
void g() {
f(add, subtract);
}
what is the role of the third T in the first line?
template<typename... T> void f(T (* ...T)(int, int);
^

this one
If I understand the syntax correctly, after ... we should see the name
of the function parameter pack, so using T seems somehow wrong to me.
Am I missing something?
Ganesh

You mean 8.3.5/10 of N2284, I assume?
| Quote: | template<typename... T> void f(T (* ...T)(int, int);
int add(int, int);
float subtract(int, int);
void g() {
f(add, subtract);
}
what is the role of the third T in the first line?

Ah, looks like a typo. That was a lower-case 't' in the original
document. I've reported this problem to the project editor.
Thanks!
