DTWAIN_RangeGetNearestValueLong

The DTWAIN_RangeGetNearestValueLong function gets the range value that is closest to a given value.

DTWAIN_BOOL DTWAIN_RangeGetNearestValueLong (

DTWAIN_RANGE	Range,
LONG	ValueIn,
LPLONG	pValueOut,
LONG	RoundType );

Parameters

Range

A valid DTWAIN_RANGE type.

ValueIn

Value to search for.

pValueOut

Address where nearest value will be stored on return of DTWAIN_RangeGetNearestValue.

RoundType

Determines whether to round to the nearest range value, round up to the next range value, or round down to the previous range value.

Return Values

If the function succeeds, TRUE is returned. If the function fails FALSE is returned.

Comments

DTWAIN_RangeGetNearestValueLong is a specialized version of DTWAIN_RangeGetNearestValue that works with DTWAIN_RANGE that stores LONG values. The only difference between DTWAIN_RangeGetNearestValueLong and DTWAIN_RangeGetNearestValue is that the second parameter, ValueIn, is not an address, but the actual LONG value to search for.

TWAIN State Transitions

None.
