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. package System.Traces is pragma Preelaborate; type Trace_T is ( -- Events handled. -- Messages -- M_Accept_Complete, M_Select_Else, M_RDV_Complete, M_Call_Complete, M_Delay, -- Errors -- E_Missed, E_Timeout, E_Kill, -- Waiting events -- W_Call, W_Accept, W_Select, W_Completion, W_Delay, WU_Delay, WT_Call, WT_Select, WT_Completion, -- Protected objects events -- PO_Call, POT_Call, PO_Run, PO_Lock, PO_Unlock, PO_Done, -- Task handling events -- T_Create, T_Activate, T_Abort, T_Terminate); -- Send_Trace_Info procedures -- They are overloaded, depending on the parameters passed with -- the event, e.g. Time information, Task name, Accept name ... procedure Send_Trace_Info (Id : Trace_T); procedure Send_Trace_Info (Id : Trace_T; Timeout : Duration); end System.Traces;
