[ndnSIM] Fwd: Convert Name of Interest

[bouchrit leila]

Thank you Xinyu Ma for reply ,
I used this instruction and i use a hash function to return an integer but
it displays the following error:

+0.000000000s 0 ndn.Consumer:Consumer()
+0.000000000s 3 ndn.Producer:Producer()

interest conversion = /CSU/hello/%FE%01
Command
['/home/leila/ndnSIM/ns-3/build/src/ndnSIM/examples/ns3-dev-HashStrategy1-debug']
terminated with signal SIGFPE. Run it under a debugger to get more
information (./waf --run <program> --command-template="gdb --args %s
<args>").

*here is my hash function:*
size_t hashing(std::string str,int n)
{
    std::hash<std::string> hash_fn;
    size_t str_hash = ((hash_fn(str)% n));
    return str_hash;
}

thank you for help.
