------------------------------------------------------------------------------
--  Display - Specifies the display to use.
--  Name    - Specifies the name of the application.
--  Message - Specifies the type of the error message.
--  Default - Specifies the default to use if the database has no entry.
--
-- Returns a message string from the error message database.
-- These predefined Names exist:
-- "XProtoError"    - protocol error code names
-- "XlibMessage"    - message strings used internally by Xlib
-- "XRequestMajor"  - protocol request code names

------------------------------------------------------------------------------
--  Display - Specifies the display to use.
--  Kind    - Specifies the error code to look up.
--
-- Returns an Ada string whose contents describe the specific error code.
-- Equivalent to a call on X_Get_Error_Database_Text(Display,"XProtoError",
-- X_Error_Code'Image(Kind),...) if there are no extensions present.  This
-- routine also queries each active extension to see if they have anything to
-- add to the error description.

------------------------------------------------------------------------------
--  Name1   - Specifies the first part of the error name
--  Name2   - Specifies the second part of the error name
--  Default - Specifies a default error message string
--
-- Called to obtain Name1.Name2 or else Name1.Name2.1 & Name1.Name2.2 & ...
-- from Xlib's system-wide error message database.  A message may appear in the
-- database in either of two ways.  This way:
--
--      Name1.Name2 : Message Text
--
-- or else in a multipart fashion like this:
--
--      Name1.Name2.1 : First line of message
--      Name1.Name2.2 : Second line of message
--      Name1.Name2.3 : Third line of message
--          ...and so on...
--
-- If we can't find either type of entry then we return the Default value.

--
-- Changes the current error handler.  Changes either the global default
-- for all displays or else changes it just for one display.
-- Returns the previous global or display handler routine.  The handler routine
-- is allowed to return.  It must not perform any action that would change the
-- state of any X_Display.

--  Display - Specifies which display to use.
--  Handler - Specifies the new I/O error handler to use.
--
-- Changes the current I/O error handler.  Changes either the global default
-- for all displays or else changes it just for one display.
-- Returns the previous handler routine.  The handler must not return; it
-- may raise an exception if it so desires, the exception will be allowed to
-- propagate out to the enclosing application code.
-- It must not perform any action that would change the state of any
-- X_Display.  The X_Display involved in the I/O operation can be presumed to
-- be unusable at this point; it should still be closed with X_Close_Display.
-- Other X_Displays still existing in Xlib will continue to
-- function (unless the basic problem is that the X server is dead).
