NAME
  XClientMessageEvent -	ColormapNotify event structure

STRUCTURES
  The structure	for _C_l_i_e_n_t_M_e_s_s_a_g_e events contains:

  typedef struct {
	  int type;	  /* ClientMessage */
	  unsigned long	serial;		  /* # of last request processed by server */
	  Bool send_event;		  /* true if this came from a SendEvent	request	*/
	  Display *display;		  /* Display the event was read	from */
	  Window window;
	  Atom message_type;
	  int format;
	  union	{
		  char b[20];
		  short	s[10];
		  long l[5];
		  } data;
  } XClientMessageEvent;

  When you receive this	event, the structure members are set as	follows.

  The type member is set to the	event type constant name that uniquely iden-
  tifies it.  For example, when	the X server reports a _G_r_a_p_h_i_c_s_E_x_p_o_s_e event
  to a client application, it sends an _X_G_r_a_p_h_i_c_s_E_x_p_o_s_e_E_v_e_n_t structure with
  the type member set to _G_r_a_p_h_i_c_s_E_x_p_o_s_e.  The display member is	set to a
  pointer to the display the event was read on.	 The send_event	member is set
  to _T_r_u_e if the event came from a _S_e_n_d_E_v_e_n_t protocol request.	The serial
  member is set	from the serial	number reported	in the protocol	but expanded
  from the 16-bit least-significant bits to a full 32-bit value.  The window
  member is set	to the window that is most useful to toolkit dispatchers.

  The message_type member is set to an atom that indicates how the data
  should be interpreted	by the receiving client.  The format member is set to
  8, 16, or 32 and specifies whether the data should be	viewed as a list of
  bytes, shorts, or longs.  The	data member is a union that contains the
  members b, s,	and l.	The b, s, and l	members	represent data of 20 8-bit
  values, 10 16-bit values, and	5 32-bit values.  Particular message types
  might	not make use of	all these values.  The X server	places no interpreta-
  tion on the values in	the window, message_type, or data members.
