#include <evo/net_interface.h>

Detailed Description

Query network adapter interfaces from OS.

Use Iter to iterate through interfaces and addresses
The same interface may be returned multiple times with different address (IPv4, IPv6, etc)
Destroying this invalidates all iterators using it

Example

#include <evo/net_interface.h>
#include <evo/iosock.h>
#include <evo/string.h>
#include <evo/io.h>
using namespace evo;
static Console& c = con();
int main() {
    String ipstr;
    NetworkInterfaces interfaces;
    for (NetworkInterfaces::Iter iter(interfaces); iter; ++iter) {
        if (SocketAddressIp::check(iter->addr)) {
            SocketAddressIp addr(iter->addr);
            addr.format(ipstr.clear());
            c.out << iter->name << '\t' << ipstr << NL;
        }
    }
}

Member Typedef Documentation

◆ Iter

typedef IteratorFw<NetworkInterfaces>::Const Iter

Iterator (const) - IteratorFw.

◆ SysItem

typedef struct ifaddrs SysItem

System interface item.

Constructor & Destructor Documentation

◆ NetworkInterfaces()

NetworkInterfaces	(	int	family = `AF_UNSPEC`,
		bool	active = `true`
	)

inline

Constructor queries OS for interfaces.

Use Iter to iterate through interfaces, which will reference allocated interface data

Parameters

family	Filter by address family, AF_UNSPEC for all
active	Find active interfaces, false for all interfaces

◆ ~NetworkInterfaces()

~NetworkInterfaces ( )

inline

Destructor frees interface data.

Any iterators referencing interface data are invalidated
