-- This package implements functions to format run-time traces
package System.Traces.Format is
Max_Size : constant Integer := 128;
-- Event messages' maximum size.
subtype String_Trace is String (1 .. Max_Size);
-- Specific type in which trace information is stored. An ASCII.NUL
-- character ends the string so that it is compatible with C strings
-- which is useful on some targets (eg. VxWorks)
-- These private functions handles String_Trace formatting
function Format_Trace (Source : String) return String_Trace;
-- Put a String in a String_Trace, truncates the string if necessary.
-- Similar to Head( .. ) found in Ada.Strings.Bounded
function Append
(Source : String_Trace;
Annex : String)
return String_Trace;
pragma Inline (Append);
-- Concatenates two string, similar to & operator from Ada.String.Unbounded
procedure Send_Trace (Id : Trace_T; Info : String);
-- This function (which is a subunit) send messages to external programs
end System.Traces.Format;
