/** Use variadic templates in fixed-size templated classes.
*
* Works around a compiler bug (was a language requirement on a previous
* draft of the standard).
*/
template<template class T, class… Args>
struct from_variadic
{
typedef T type;
};

To use, simply do:

typedef typename from_variadic::type arg_types;
boost::mpl::for_each(functor);

Taken from here (with a minor compilation error corrected): http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35722#c12


void *pFun = reinterpret_cast(&f1);
boost::fusion::invoke(pFun, boost::fusion::make_vector());


PS Anyway, surely the task should have many possible solutions, including elegant and simple ones, like the one you provided, even if they don’t match the task precisely So thanks for that!

#include

void f1() {
std::cout << "f1()" << std::endl;
}

int f2() {
std::cout << "f2()" << std::endl;
return 3;
}

int f3(int v) {
std::cout << "f3()" << std::endl;
return f2()+v;
}

int main() {
/** without args */
boost::fusion::invoke(&f1, boost::fusion::make_vector());

/** without args */
boost::fusion::invoke(&f2, boost::fusion::make_vector());

/** with args */
int r = boost::fusion::invoke(&f3, boost::fusion::make_vector(3));
std::cout << r << std::endl;
}

you are welcome to look at this link: http://blog.shandyba.com/2010/03/27/rcf-1-2-openssl/.

This example 100% works and, well, I don’t experience any freezings… So give it a try!

Good luck!

WUT? Have you been taught about tautology at school? Though, despite this, very interesting article. Keep it up!
