[asio-users] ip::address::from_string() not working

[Darren Cook]

ip::address's from_string() function does not seem to be working; it
gives me 0.0.0.0 whatever string I pass.

A very minimal reproducible example below, it outputs:
Set host to 0.0.0.0

I'm using boost 1.40 (ubuntu 10.04). Google is strangely quiet; so I
guess I'm doing something wrong??

//Compile and run with "g++ test.cpp -lboost_system;./a.out"

#include <iostream>
#include <boost/asio.hpp>

int main(int argc, char* argv[])
{
boost::asio::ip::address host;
host.from_string("127.0.0.1");
std::cout<<"Set host to "<<host<<"\n";
return 0;
}

'boost::asio::ip::address::from_string()' is a static member function:
http://www.boost.org/doc/libs/1_48_0/doc/html/boost_asio/reference/ip__address/from_string.html

usage:
#include <iostream>
#include <boost/asio.hpp>

int main(int argc, char* argv[])
{
boost::asio::ip::address host =
boost::asio::ip::address::from_string("127.0.0.1");
std::cout<<"Set host to "<<host<<"\n";
return 0;
}

boost::asio::ip::address host =
boost::asio::ip::address::from_string("127.0.0.1");

Thanks niXman, that worked! (I had tried using it statically, after
finding an example on the web somewhere, but I got a segmentation error;
it must have been an unlucky coincidence.)
