This procedure is used from within the Runtime to send 42-- debug informations. 43 44-- This primitive is overloaded in System.Traces.Tasking and this package 45 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 .. 48 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). 52 53-- To add a new target, just adapt System.Traces.Send to your own purposes 54 55package System.Traces is 56 pragma Preelaborate; 57 58 type Trace_T is 59 ( 60 -- Events handled 61 62 -- Messages 63 64 M_Accept_Complete, 65 M_Select_Else, 66 M_RDV_Complete, 67 M_Call_Complete, 68 M_Delay, 69 70 -- Errors 71 72 E_Missed, 73 E_Timeout, 74 E_Kill, 75 76 -- Waiting events 77 78 W_Call, 79 W_Accept, 80 W_Select, 81 W_Completion, 82 W_Delay, 83 WU_Delay, 84 85 WT_Call, 86 WT_Select, 87 WT_Completion, 88 89 -- Protected objects events 90 91 PO_Call, 92 POT_Call, 93 PO_Run, 94 PO_Lock, 95 PO_Unlock, 96 PO_Done, 97 98 -- Task handling events 99 100 T_Create, 101 T_Activate, 102 T_Abort, 103 T_Terminate); 104 105 -- Send_Trace_Info procedures 106 107 -- They are overloaded, depending on the parameters passed with 108 -- the event, e.g. Time information, Task name, Accept name ... 109 110 procedure Send_Trace_Info (Id : Trace_T); 111 112 procedure Send_Trace_Info (Id : Trace_T; Timeout : Duration); 113 114end System.Traces; 115
