The arguments are as follows:
-h
Display a list of performance counter events available on the system.
-C
Cancel any performance counters that are currently running.
-c event
Count the event specified by event while running the command.
DIAGNOSTICS

BUGS
The pmc command currently only supports performance-monitoring counters on the i386 architecture.
