Arguments
The arguments to cpc probes are listed in table below.
Table 11-7 Probe Arguments
arg0
| The program counter (PC) in the kernel at the time that the probe fired,
or 0 if the current process was not executing in the kernel at the time that
the probe fired
|
arg1
| The PC in the user-level process at the time that the probe fired, or
0 if the current process was executing at the kernel at the time that the
probe fired
|
|
As the descriptions imply, if arg0 is non-zero then arg1 is zero; if arg0 is zero then arg1 is
non-zero.
