+ * key and gate is open. If it's a command key, then twiddle
+ * the gate state as required (optional, see below).
+ *
+ * This routine implements an optional user specified command key
+ * that can be used to close the input pipe into the server
+ * while a client command is generated. The keypress of the
+ * command key places this routine in command mode, the keyrelease
+ * exits command mode.
+ *
+ * A keypress of the command key followed by the
+ * optionally specified lock key will place this routine in continuous
+ * command mode until the command key and lock key are pressed again
+ * to exit command mode. In the locked state, the client interprets
+ * keystrokes as it wishes, as commands or as input to a prior command.
+ *
+ * Both mechanisms can be used alternately.
+ *
+ * IMPLICIT INPUTS :
+ *
+ * penv->cur.data_config_cmd_key :
+ * This is the keycode of the key that is used to stop
+ * and restart the transmission of intercepted input
+ * events to the server. If specified, the gate_state
+ * flag will be set or cleared depending on the state of
+ * the command_key.
+ *
+ * penv->cur.data_config_flags_data.XETrapCmdKeyMod:
+ * This is the value of the mode in which the command_key
+ * will operate. It currently has two values: MODIFIER and
+ * COMMAND_LOCK. MODIFIER mode clears gate_state on
+ * keypress, and sets gate_state on keyrelease.
+ * COMMAND_LOCK mode toggles gate_state on
+ * or off.
+ *
+ * gate_closed:
+ * A flag that is set/cleared in the xtrap_keyboard
+ * routine that indicates whether intercepted input
+ * should be passed to the server at any particular
+ * instance.
+ *
+ *
+ * next_key:
+ * This variable tracks the state of the next key to be
+ * pressed or released. It allows the checking of double
+ * presses of the command key to be sent to the server and
+ * keeps good state order when the command key is used.
+ *
+ * key_ignore:
+ * This variable indicates whether or not the specific
+ * key should be ignored for subsequent server processing.

+ * This module is the device independent module responsible for all
+ * routines required for proper communication in a heterogeneous
+ * networking environment (i.e. client & server on different endian
+ * machines). The bulk of this module is patterned after X11/R4's
+ * server/dix/swapreq.c ; however, they infact swap fields
+ * in the exact opposite order since XTrap requires "unswapped" data
+ * to become "swapped" before sending it to a "swapped" client.
