/* Definitions for the X window system used by server and c bindings */

/*
 * This packet-construction scheme makes the following assumptions:
 *
 * 1. The compiler is able
 * to generate code which addresses one- and two-byte quantities.
 * In the worst case, this would be done with bit-fields.  If bit-fields
 * are used it may be necessary to reorder the request fields in this file,
 * depending on the order in which the machine assigns bit fields to
 * machine words.  There may also be a problem with sign extension,
 * as K+R specify that bitfields are always unsigned.
 *
 * 2. 2- and 4-byte fields in packet structures must be ordered by hand
 * such that they are naturally-aligned, so that no compiler will ever
 * insert padding bytes.
 *
 * 3. All packets are hand-padded to a multiple of 4 bytes, for
 * the same reason.
