Bits 13-15 = 0 HO_Init_Here
Starts a trace of the current stack with the context of this call to
HIST_INIT_. The context parameter is ignored in this case.
= 1 HO_Init_uContext
Uses the uContext structure whose address is passed in the
context parameter. A uContext structure is a structure of type
UCONTEXT_T that is passed to a signal handler installed by the
SIGACTION_INIT_ or SIGACTION_SUPPLANT_ procedure.
HIST_INIT_ initializes the trace at the point where the signal was
generated. See “Protected contexts” under “Considerations” for
more information.
