+ -- Error Message Text and Message Insertion Characters --
+ ---------------------------------------------------------
+
+ -- Error message text strings are composed of letters, digits and the
+ -- special characters space, comma, period, colon and semicolon,
+ -- apostrophe and parentheses. Special insertion characters can also
+ -- appear which cause the error message circuit to modify the given
+ -- string as follows:
+
+ -- Insertion character % (Percent: insert file name from Names table)
+ -- The character % is replaced by the text for the file name specified
+ -- by the Name_Id value stored in Error_Msg_Name_1. The name is always
+ -- enclosed in quotes. A second % may appear in a single message in
+ -- which case it is similarly replaced by the name which is specified
+ -- by the Name_Id value stored in Error_Msg_Name_2.
+
+ -- Insertion character & (Ampersand: insert unit name from Names table)
+ -- The character & is replaced by the text for the unit name specified
+ -- by the Name_Id value stored in Error_Msg_Name_1. The name is always
+ -- enclosed in quotes. A second & may appear in a single message in
+ -- which case it is similarly replaced by the name which is specified
+ -- by the Name_Id value stored in Error_Msg_Name_2.
+
+ -- Insertion character # (Pound: insert non-negative number in decimal)
+ -- The character # is replaced by the contents of Error_Msg_Nat_1
+ -- converted into an unsigned decimal string. A second # may appear
+ -- in a single message, in which case it is similarly replaced by
+ -- the value stored in Error_Msg_Nat_2.
+
+ -- Insertion character ? (Question mark: warning message)
+ -- The character ?, which must be the first character in the message
+ -- string, signals a warning message instead of an error message.
+
+ -----------------------------------------------------
+ -- Global Values Used for Error Message Insertions --
+ -----------------------------------------------------
+
+ -- The following global variables are essentially additional parameters
+ -- passed to the error message routine for insertion sequences described
+ -- above. The reason these are passed globally is that the insertion
+ -- mechanism is essentially an untyped one in which the appropriate
+ -- variables are set dependingon the specific insertion characters used.
+
+ Error_Msg_Name_1 : Name_Id;
+ Error_Msg_Name_2 : Name_Id;
+ -- Name_Id values for % insertion characters in message
+
+ Error_Msg_Nat_1 : Nat;
+ Error_Msg_Nat_2 : Nat;
+ -- Integer values for # insertion characters in message
+
+ ------------------------------
+ -- Error Output Subprograms --
+ ------------------------------
+
+ procedure Error_Msg (Msg : String);
+ -- Output specified error message to standard error or standard output
+ -- as governed by the brief and verbose switches, and update error
+ -- counts appropriately
+
+ procedure Error_Msg_Info (Msg : String);
+ -- Output information line. Indentical in effect to Error_Msg, except
+ -- that the prefix is info: instead of error: and the error count is
+ -- not incremented. The prefix may be suppressed by setting the global
+ -- variable Info_Prefix_Suppress to True.
+
+ procedure Error_Msg_Output (Msg : String; Info : Boolean);
+ -- Output given message, with insertions, to current message output file.
+ -- The second argument is True for an info message, false for a normal
+ -- warning or error message. Normally this is not called directly, but
+ -- rather only by Error_Msg or Error_Msg_Info. It is called directly
+ -- when the caller must control whether the output goes to stderr or
+ -- stdout (Error_Msg_Output always goes to the current output file).
+
+ procedure Finalize_Binderr;
+ -- Finalize error output for one file
+
+ procedure Initialize_Binderr;
+ -- Initialize error output for one file
+
+end Binderr;
