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