This change is needed to share the functionality between the core library and the SDK library. We want to support building/installing just the SDK without having a dependency on the core library which adds additional dependencies.
FairMQ Tools
Contains common tools for use by FairMQ and/or users.
fair::mq::tools::getHostIPs
Fills a map with the network interfaces and their IP addresses available on the current host.
Example usage
#include <map>
#include <string>
#include <iostream>
#include <fairmq/Tools.h>
void main()
{
std::map<string,string> IPs;
fair::mq::tools::getHostIPs(IPs);
for (std::map<string,string>::iterator it = IPs.begin(); it != IPs.end(); ++it)
{
std::cout << it->first << ": " << it->second << std::endl;
}
}
Example Output
eth0: 123.123.1.123
ib0: 123.123.2.123
lo: 127.0.0.1
