14 Verifying IPv6 Installation
The following code fragment shows how an application can determine programmatically
whether IPv6 is implemented on HP-UX. An application can check the existence of the
/dev/ip6 device file at compile-time and/or run-time to determine whether IPv6 APIs and the
IPv6 stack are on the system. If /dev/ip6 does not exist, an application continues to use IPv4
