| -- 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. |
