socket programming in hpux platform by using AF_ROUTE family.

[jgobbur]

Hi,
In hpux I am unable to use AF_ROUTE family yo create socket.
i.e.
cc -I. -I../mDNSCore -I../mDNSShared -DPID_FILE=mdnsPosixOracleGetPidFile\(\"/tmp/.oracle/mdnsd.pid
\"\) -DMDNS_UDS_SERVERPATH=mdnsPosixOracleGetUDSServerPath\(\"/tmp/.oracle/mdnsd\"\) -DNOT_HAVE_DAEM

It is failing at socket create.
i.e.
*pFD = socket( AF_ROUTE, SOCK_RAW, 0);

[Torsten.]

Hard to suggest without the source, but did you check if you have all includes?

[jgobbur]

error related source code:
// Open a socket that will receive interface change notifications
1281 mDNSlocal mStatus OpenIfNotifySocket( int *pFD)
1282 {
1283 *pFD = socket( AF_ROUTE, SOCK_RAW, 0);
1284
1285 if ( *pFD < 0)
1286 return mStatus_UnknownErr;
1287
1288 // Configure read to be non-blocking because inbound msg size is not known in advanc
e
1289 (void) fcntl( *pFD, F_SETFL, O_NONBLOCK);
1290
1291 return mStatus_NoError;
1292 }

But in /usr/include/sys/socket.h header file we don't AF_ROUTE family in hpux machine.

[jgobbur]

Already header files included
328 #include
329 #include
330 #include
331 #include
332 #include
333 #include
334 #include

[Laurent Menase]

It is only available on 11.31 (11iv3)
and according to man 7p route:
#include
#include
#include
#include

How to do it in 11.23 version.

[jgobbur]

IS there equivalent program to write in 11.23 OS version.

[Laurent Menase]

there is no routing events mechanisms on 11.23
you can only poll the routing table periodically
using ioctl over AF_INET/SOCK_RAW sockets
or popen("netstat -nr") or popen("ndd -get /dev/ip ip_ire_status")

or using the private api libnm.

[Laurent Menase]

supported ioctl() on 11.23 are:
SIOCADDRT
SIOCDELRT
SIOCADDRTEX
SIOCDELRTEX
SIOCFLUSHRT
SIOCGRTENTRY

over a AF_INET/SOCK_RAW socket,
