In QNX 6.1, I can use “route -n -get destination gateway” to look up and
display the route for a destination. The “get” option is no longer
available in QNX 6.2. What’s been replaced with ?
Thanks,

It works for me in 6.2.1. The syntax is:
route get
route -n get

It’s documented in 6.1 and it works in 6.1. But it’s not documented in 6.2 and
I am
running 6.2 ( not 6.2.1), it’s not working in 6.2.
Maybe it’s added back to 6.2.1. Any one can verify this?
Thanks,

I’m running 6.21. It works for me.

We have verified that the “route get” command works on QNX6.1 and QNX 6.2.1. But it
didn’t work on QNX 6.2.
How can we get this supported on QNX 6.2?

If you copy the route utility from 6.2.1 it “should” work.

This is not going work since I don’t know what version of QNX my program will run. I use
the “route get” command to get interface name and gateway address for a giving ip
address. For Tiny TCP, I parse the /proc/ipstat file to get these information. What I
should really ask is how to get interface name, and gateway address of a giving ip
address programmatically? That will take care both tiny and full TCPIP.
Appreciate any help.

The best way to do this for the full stack is to use a routing
socket directly from C. See the thread entitled “Reading routing
entries” in this group for an example.

Sean, Thanks for your help. I have tried the sample you suggested. I works on getting the
default route for full tcp stack, but not on tiny tcp. Is there any way that I can write the
code so that it can be used for both tiny and full tcp?
Secondly, I am having difficulty on getting the information that I need using the following
code. I want to get an interface name and gateway address for an given ip address. Please

Yes, routing sockets are only supported by the full stack.
If the socket() calls fails, you are probably running
under the tiny stack or no stack. If under the tiny stack,
the only way to get the current routes is via /proc/ipstats
as you are currently doing.
