## Define Documentation

#define PCAP_SAMP_1_EVERY_N 1

It defines that only 1 out of N packets must be returned to the user.

In this case, the 'value' field of the 'pcap_samp' structure indicates the number of packets (minus 1) that must be discarded before one packet got accepted. In other words, if 'value = 10', the first packet is returned to the caller, while the following 9 are discarded.

#define PCAP_SAMP_FIRST_AFTER_N_MS 2

It defines that we have to return 1 packet every N milliseconds.

In this case, the 'value' field of the 'pcap_samp' structure indicates the 'waiting time' in milliseconds before one packet got accepted. In other words, if 'value = 10', the first packet is returned to the caller; the next returned one will be the first packet that arrives when 10ms have elapsed.

#define PCAP_SAMP_NOSAMP 0

No sampling has to be done on the current capture.

In this case, no sampling algorithms are applied to the current capture.
