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 (e.g. 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;
