ADLINK HSL-AI16AO2-M-VV/-AV - Manual (Page 111)

98 HSL Function Library
enable: Enables (0) or disables (1) the Di interrupt.
time_out_ms: Specifies the time-out interval in milliseconds. The
function returns if the interval elapses, even when the interrupt is
non-signaled. If time_out_ms is zero, the function tests the Di state
and returns immediately. If time_out_ms is -1, the function's time-
out interval does not elapses (infinite).
