NAME
       PR_SET_TIMING - set the process timing mode

LIBRARY
       Standard C library (libc, -lc)

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

       int prctl(PR_SET_TIMING, long mode);

DESCRIPTION
       Set whether to use (normal, traditional) statistical process timing or
       accurate timestamp-based process timing, by passing
       PR_TIMING_STATISTICAL or PR_TIMING_TIMESTAMP to mode.

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

ERRORS
       EINVAL mode is not PR_TIMING_STATISTICAL.

STANDARDS
       Linux.

HISTORY
       Linux 2.6.0.

CAVEATS
       PR_TIMING_TIMESTAMP is not currently implemented (attempting to set
       this mode will yield the error EINVAL).
