multiplier

    OpenVMS usage:floating_point
    type:         F_floating
    access:       read only
    mechanism:    by reference

    The value by which LIB$MULTF_DELTA_TIME multiplies the delta
    time. The multiplier argument is the address of an F-floating
    value containing the scalar. If multiplier is negative, the
    absolute value of multiplier is used.

 delta-time

    OpenVMS usage:date_time
    type:         quadword (unsigned)
    access:       modify
    mechanism:    by reference

    The delta time to be multiplied. The delta-time argument is
    the address of an unsigned quadword containing the number to
    be multiplied. The initial delta-time argument must be greater
    than 0. After LIB$MULTF_DELTA_TIME performs the multiplication,
    the result is returned to delta-time. (The original delta-time
    value is overwritten.)
