6 libperf-sampling - sampling interface
11 The sampling interface provides API to measure and get count for specific perf events.
13 The following test tries to explain count on `sampling.c` example.
15 It is by no means complete guide to sampling, but shows libperf basic API for sampling.
17 The `sampling.c` comes with libperf package and can be compiled and run like:
21 $ gcc -o sampling sampling.c -lperf
22 $ sudo ./sampling
36 The `sampling.c` example profiles/samples all CPUs with hardware cycles, in a
158 From this moment the cycles event is sampling.
