Re: [ns] another implementation question for ad hocs
Hi,
If your packets will be of some new packet type (i.e. ch->ptype() that is
"switched" on is something else than what is already there), you will need
to do that, or at least you will need to add a part saying
case PT_NEWP:
break;
where PT_NEWP is the new packet type. The reason for having this
format_xyz() function is if you want any protocol specific data in the
trace file (the format_xyz() function writes stuff to the trace
file). Otherwise I suppose just the above would do (but you need that
case PT_NEWP: stuff, otherwise an error will occur (unknown packet type)).
Hope this helps,
/Anders
