# PR\_TASK\_PERF\_EVENTS\_DISABLE(2)

disable or enable performance counters attached to the calling process

## 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.
