32 -- This package implements functions for traces when tasking is not involved
34 -- Warning : NO dependencies to tasking should be created here
36 -- This package, and all its children are used to implement debug
39 -- A new primitive, Send_Trace_Info (Id : Trace_T; 'data') is introduced.
40 -- Trace_T is an event identifier, 'data' are the informations to pass
41 -- with the event. This procedure is used from within the Runtime to send
42 -- debug informations.
44 -- This primitive is overloaded in System.Traces.Tasking and this package
46 -- Send_Trace_Info calls Send_Trace, in System.Traces.Send, which is target
47 -- dependent, to send the debug informations to a debugger, stream ..
49 -- To add a new event, just add them to the Trace_T type, and write the
50 -- corresponding Send_Trace_Info procedure. It may be required for some
51 -- target to modify Send_Trace (e.g. VxWorks).
53 -- To add a new target, just adapt System.Traces.Send to your own purposes
55 package System
.Traces
is
89 -- Protected objects events
98 -- Task handling events
105 -- Send_Trace_Info procedures
107 -- They are overloaded, depending on the parameters passed with
108 -- the event, e.g. Time information, Task name, Accept name ...
