23 /* A very basic example of how to get the network statistics from the system
24 * and diaply them. Also it adds up all the traffic to create and print out
25 * a total
26 * Takes several arguments :
27 * -d <number> Takes the number of seconds to wait to get traffic sent since last call
28 * Note, this is not network traffic per second. Its the traffic since last
29 * call. If you want it traffic per second averaged over time since last call
30 * You need to divide against the time since last time this was called. The time
31 * between 2 calls is stored in systime in the network_stat_t structure.
32 * -b Display in bytes
33 * -k Display in kilobytes
34 * -m Display in megabytes
