In the wrapper functions (setparam_xxx)
for ex something like this:

int setparam_uint64(pcap_t * pcap, char* param, uint64_t value)
{
  char[64] buf;
  sprintf(buf, "%lu", value);
  return pcap->setparam_op(param, buf);  //Add check for NULL op
}

That we use only one function ptr to set and get parameter values,
which uses char* as parameters.
