6 libperf-counting - counting interface
10 The counting interface provides API to measure and get count for specific perf events.
12 The following test tries to explain count on `counting.c` example.
14 It is by no means complete guide to counting, but shows libperf basic API for counting.
16 The `counting.c` comes with libperf package and can be compiled and run like:
20 $ gcc -o counting counting.c -lperf
21 $ sudo ./counting
29 The `counting.c` example monitors two events on the current process and displays
158 From this moment events are counting and we can do our workload.
