PR_SET_TIMING(2const)                              PR_SET_TIMING(2const)

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).
