Macro Definition Documentation

GUAC_WOL_PACKET_SIZE

#define GUAC_WOL_PACKET_SIZE   102

The size of the magic Wake-on-LAN packet to send to wake a remote host.

This consists of 6 bytes of 0xFF, and then the MAC address repeated 16 times. https://en.wikipedia.org/wiki/Wake-on-LAN#Magic_packet

GUAC_WOL_PORT

#define GUAC_WOL_PORT   9

The port number that the magic packet should contain as the destination.

In reality this doesn't matter all that much, since the packet is not usually processed by a full IP stack, but defining one is considered a standard practice.
