PR_TASK_PERF_EVENTS_DISABLE(2const)        PR_TASK_PERF_EVENTS_DISABLE(2const)

NAME
       PR_TASK_PERF_EVENTS_DISABLE, PR_TASK_PERF_EVENTS_ENABLE - disable or
       enable performance counters attached to the calling process

LIBRARY
       Standard C library (libc, -lc)

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

       int prctl(PR_TASK_PERF_EVENTS_DISABLE);
       int prctl(PR_TASK_PERF_EVENTS_ENABLE);

DESCRIPTION
       PR_TASK_PERF_EVENTS_DISABLE
              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.

RETURN VALUE
       On success, 0 is returned.  On error, -1 is returned, and errno is set
       to indicate the error.

STANDARDS
       Linux.

HISTORY
       Linux 2.6.31.

       Originally called PR_TASK_PERF_COUNTERS_DISABLE and
       PR_TASK_PERF_COUNTERS_ENABLE; renamed (retaining the same numerical
       value) in Linux 2.6.32.
