HIST_FORMAT_ Procedure
HO_ShowProtected, and HO_NoSuppress, the trace would look something like
this:
Returned Text Explanation
HANDLER + 0x28 (UCr) Indicates the current procedure (that
is, the signal handler) and the offset.
PK_SIG_HANDLER_JACKET_
+ 0x54 (SLr)
Indicates the procedure that called the
handler and the offset of the call. The
system procedure that called the
handler is considered a transition
frame and is suppressed by default.
--- Denotes a break in the calling
sequence. In this case,
PRIV_PROC_ did not call
PK_SIG_HANDLER_JACKET_; the
operating system intervened in
response to a trap.
PRIV_PROC_ + 0x5C (SCr) Indicates the procedure in which and
the offset where the trap occurred.
This context is the primary context in
the uContext generated at the time of
the trap. It is found automatically
when tracing through the special jacket
procedure. This context is suppressed
unless the HO_ShowProtected option
of HIST_INIT_ is in effect.
