NAME    [Toc]    [Back]

       getclock - Get current value of system-wide clock

SYNOPSIS    [Toc]    [Back]

       #include <sys/timers.h>

       int getclock(
               int clktyp,
               struct timespec *tp );

LIBRARY    [Toc]    [Back]

       Standard C Library (libc)

PARAMETERS    [Toc]    [Back]

       Identifies  a  system-wide  clock.   Points  to a timespec
       structure space where the current value of the system-wide
       clock is stored.

DESCRIPTION    [Toc]    [Back]

       The  getclock()  function  sets  the  current value of the
       clock specified by clktyp into the location pointed to  by
       the tp parameter.

       The clktyp parameter is given as a symbolic constant name,
       as defined in the  sys/timers.h  include  file.  Only  the
       TIMEOFDAY  symbolic  constant,  which specifies the normal
       time-of-day clock to access for system-wide time, is  supported.

       For  the  clock specified by TIMEOFDAY, the value returned
       by this function is the elapsed time since the epoch.  The
       epoch is referenced to 00:00:00 UTC (Coordinated Universal
       Time) 1 Jan 1970.

       The getclock()  function  returns  a  timespec  structure,
       which  is  defined in the sys/timers.h header file. It has
       the following members:
