## NAME

           clock_gethrtime - get high resolution time using the spec
           ified clock

## SYNOPSIS

           #include <rtl_time.h>

           hrtime_t clock_gethrtime(clockid_t clock);

## DESCRIPTION

           This function is a non-portable Real-Time Linux extension.
           clock_gethrtime  returns the clock reading in nanoseconds.
           This is a convenience function for clock_gettime(3)

           hrtime_t is a 64-bit signed integer.

## NOTES

           The following clocks are  supported  by  this  release  of
           Real-Time Linux:

           CLOCK_REALTIME
                  The standard POSIX clock.

           CLOCK_8254
                  The clock that is used on non-SMP x86 systems.

           CLOCK_APIC
                  The local APIC clock on SMP x86 systems.
