HIST_FORMAT_ Procedure
An example trace in the TNS/R environment:
An example trace in the TNS/E environment:
In the next example,
doer was called in unprivileged state. For this trace:
•
options equals HO_Init_uContext + HO_OneLine, and the address of the
handler’s context is passed in the
context parameter of HIST_INIT_.
•
FormatSelect equals HF_trace (the default value) + HF_LocLineRISC.
The HO_OneLine option causes the name and register states to appear on the same
line. Only one frame is reported because HIST_GETPRIOR_ is not called.
