The code below is designed to run indefinitely with one coroutine. I have, however, used one integer parameter to the subroutine f(). The integer parameter is, however, not needed. Yet I can not seem to remove the integer parameter and get the sample to compile.
Can I remove the integer parameter? yes If so, how should it be coded? This version compiles for me:
#include <iostream> #include <boost/coroutine/all.hpp> #include <boost/bind.hpp> typedef boost::coro::coroutine< void() > coro_t; void f(coro_t::self_t & self) // 2nd. arg of type int removed { for(;;) { std::cout << "In coroutine" << std::endl; self.yield(); } } int main(int, char**) { coro_t c( boost::bind(f, _1) ); for ( ;; ) { std::cout << "In main" << std::endl; c(); } } but this second version (binding the 2nd parameter) works for me too: #include <iostream> #include <boost/coroutine/all.hpp> #include <boost/bind.hpp> typedef boost::coro::coroutine< void() > coro_t; void f(coro_t::self_t & self, int i) { for(;;) { std::cout << "In coroutine, i == " << i << std::endl; self.yield(); } } int main(int, char**) { coro_t c( boost::bind(f, _1, 1000) ); for ( ;; ) { std::cout << "In main" << std::endl; c(); } } hope I could help regards, Oliver
