NAME
    ReadEClock -- Get the current value of the E-Clock. (V36)
SYNOPSIS
    E_Freq = ReadEClock( Dest )
    D0                   A0
    ULONG ReadEClock ( struct eclockval * );
FUNCTION
    This routine calculates the current 64 bit value of the E-Clock
    and stores it in the destination eclockval structure. the count
    rate of the E-Clock is also returned.
    A0 will be left unchanged
    This is a low overhead function designed so that very short
    intervals may be timed.
INPUTS
    Dest -- pointer to an eclockval structure.
RETURNS
    Dest -- the eclockval structure will contain the e-clock time
    E_Freq -- The count rate of the E-Clock (tics/sec).
NOTES
    This function may be called from interrupts.
