       to the calling process

LIBRARY

SYNOPSIS

       #include <linux/prctl.h>  /* Definition of PR_* constants */

              Disable  all  performance  counters  attached  to  the  calling process, regardless of whether the
              counters were created by this process or another process.  Performance  counters  created  by  the
              calling process for other processes are unaffected.

       PR_TASK_PERF_EVENTS_ENABLE
              The  converse  of PR_TASK_PERF_EVENTS_DISABLE; enable performance counters attached to the calling
              process.
