35 -- This package implements functions for traces when tasking is not involved
37 -- Warning : NO dependencies to tasking should be created here
39 -- This package, and all its children are used to implement debug
42 -- A new primitive, Send_Trace_Info (Id : Trace_T; 'data') is introduced.
43 -- Trace_T is an event identifier, 'data' are the informations to pass
44 -- with the event. Thid procedure is used from within the Runtime to send
45 -- debug informations.
47 -- This primitive is overloaded in System.Traces.Tasking and this package.
49 -- Send_Trace_Info calls Send_Trace, in System.Traces.Send, which is trarget
50 -- dependent, to send the debug informations to a debugger, stream ..
52 -- To add a new event, just add them to the Trace_T type, and write the
53 -- corresponding Send_Trace_Info procedure. It may be required for some
54 -- target to modify Send_Trace (eg. VxWorks).
56 -- To add a new target, just adapt System.Traces.Send to your own purpose.

.Traces
is

100 -- Task handling events
107 -- Send_Trace_Info procedures
109 -- They are overloaded, depending on the parameters passed with
110 -- the event, e.g. Time information, Task name, Accept name ...
