Guardian Procedure Calls Reference Manual

An example trace in the TNS/R environment:
xtracer + 0x60 (UCr)
handler + 0x170 (UCr)
PK_SIG_HANDLER_JACKET_ + 0x68 (SLr)
---
caller + 0x28 (UCr)
HIST_TEST_ACTOR_ + 0x2BC (UCr)
PROGRAM + 0x510 (UCr)
An example trace in the TNS/E environment:
options =HO_Init_Here + HO_ShowProtected + HO_NoSuppress
FormatSelect = HF_trace
xtracer + 0xF0 (UCr)
handler + 0x220 (UCr)
$UD_S__SigHandlerJacket + 0x3B0 (SLr)
---
caller + 0x100 (SLr)
HIST_TEST_ACTOR_ + 0xB0 (UCr)
main + 0xAD0 (UCr)
_MAIN + 0x160 (UCr)
Example Traces: Case 3
The next sequence of examples is similar to case 1, except:
• The process is unprivileged when it generates a SIGSEGV signal.
• The signal occurs in millicode (a move-bytes operation).
In the first trace:
• options equals HO_Init_uContext + HO_NoSuppress, and the address of the handler's
context is passed in the context parameter of HIST_INIT_.
• FormatSelect equals HF_trace (the default value).
An example trace in the TNS/R environment:
pc=%h7E0014C4 (Milli)
doer + 0xB0 (UCr)
HIST_TEST_ACTOR_ + 0x304 (UCr)
PROGRAM + 0x514 (UCr)
