| -- This package implements functions to format run-time traces |
| |
| package System.Traces.Format is |
| pragma Preelaborate; |
| |
| Max_Size : constant Integer := 128; |
| -- Maximum size if event messages |
| |
| 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 (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; |
