It's a bit hard to tell without seeing your code, but note that
the packet object can build two kinds of packets: one with just a simple
command, or a packet with command + data. I'm assuming that GetEventlogEntry()
is creating a command + data packet.
If so, then you'll want to pass the argument to GetEventlogEntry() containing
the incrementing count.
For example, from a different function:
int JLPacket::GetSubDir(uint16_t id)
{
SimpleCmd(SB_COMMAND_JL_GET_SUBDIR, 0, 2);
return BigEndianData(id);
}
SimpleCmd() gives the command, and the amount of data to follow in the
next data packet (2). The data is given as a uint16_t big endian value.
The combination of the two, creates a JLPacket object with two chunks
of data to send.
Hopefully I'm answering the right question here. :-)
