Yep. Or with the latest version where the function has been modified
to support IPv6:

 #include <pj/addr_resolv.h>

 pj_sockaddr addr;
 int af;

 af = pj_AF_INET();  // or pj_AF_INET6 for IPv6

 if (pj_gethostip(af, &addr) == PJ_SUCCESS) {
    char ipaddr[PJ_INET6_ADDRSTRLEN];

    printf("my ip=%s\n",
            pj_sockaddr_print(&addr, ipaddr, sizeof(ipaddr), 0));
 }

Cheers
