Hi,

Is there a systemtap equivalent of inet_addr?

Thanks,

Hi Paddie,

There are functions for dealing with ip addresses. There is documentation describing them in: 

http://sourceware.org/systemtap/tapsets/

You might take a look at the examples to see how the functions are used in the network examples:

Hi,

Was the example example code in tcpipstat.stp sufficient for what you are doing? Or did you have to rewrite a lot?

Any suggestions on what this tapset interface should look like?

The code in tcpipstat.stp is fine for my purposes. It would
require some work to have it mirror POSIX's inet_addr
however. The interface would simply be:

inet_addr:long(addr:string)
