taking address of a template method

hello,

i have the following problem: taking the pointer of a particular
instantiation of template member function A::f. i have no idea of how
achieve in the intent. :(

any halp or hint would be very appreciated.

cheers
domenico

struct A
{
template <typename T>
void f(const T& t) { ... }
};

void g(void (A::* f)(const int&))
{
...
}

int main()
{
void (A::* x)(const int&) = &(A::template f<int>);
g(x);

...
}

This:

struct A
{
template <typename T> void f(const T& t) {}
};

void g(void (A::*f)(const int&))
{
A a;
(a.*f)(42);
}

int main()
{
void (A::* x)(const int&) = &A::f<int>;
g(x);
}

compiles for me, as expected.

What error messages do you get, if any?

none. thanks to your confirmation i found it was my fault elsewhere.

i do not even need to explicate the instantiation, compiler guesses it
from the signature of the pointer x.

many thanks again
