/* * aim_im.c * * The routines for sending/receiving Instant Messages. * * Note the term ICBM (Inter-Client Basic Message) which blankets * all types of genericly routed through-server messages. Within * the ICBM types (family 4), a channel is defined. Each channel * represents a different type of message. Channel 1 is used for * what would commonly be called an "instant message". Channel 2 * is used for negotiating "rendezvous". These transactions end in * something more complex happening, such as a chat invitation, or * a file transfer. * * In addition to the channel, every ICBM contains a cookie.
