H A D	libperf-counting.txt	1 libperf-counting(7) 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.
