hi,
i need to add 2 integers through a lambda object. the first integer parameter
comes from the input. the second one comes from a function that takes no
parameter and return integer. the only solution i could think of is as follows:
//////////////////////////////////////////////////////////////////
#include <iostream>
#include <sigc++.h>
int f() { return 8; }
int g(int a, int b) { return a + b; }
int main()
{
std::cerr << "y=" << sigc::bind<-1>(sigc::group((sigc::_1 +
sigc::_2),sigc::_1, sigc::group(sigc::hide<0>(sigc::ptr_fun(&f)), sigc::_2)),
0)(1) << std::endl;
}
my problem with the above solution is that i have to pass and hide sigc::_2
from f() and to use bind for the redundant input parameter. is there a better
solution?
thanks in advance,
ofer
