man socket_getifname () - get interface name
NAME
socket_getifname - get interface name
SYNTAX
#include <socket.h>
const char* socket_getifname(uint32 interface);
DESCRIPTION
socket_getifname returns the symbolic interface name for a network interface number. The returned char* is a static buffer in the libc. If you query the named for more than one interface, you have to save the name before calling socket_getifidx again.
If something goes wrong, socket_getifname returns "[unknown]".
