DTWAIN_RangeCreate

Top Previous Next

The DTWAIN_RangeCreate creates a DTWAIN_RANGE.

DTWAIN_RANGE DTWAIN_RangeCreate ( LONG RangeType );

Parameters

RangeType

This is the data type that the created DTWAIN_RANGE will store.

Return Values

If the function succeeds, a new DTWAIN_RANGE is returned. Otherwise, NULL is returned.

Comments

The DTWAIN_RangeCreate function returns a new DTWAIN_RANGE of the type RangeType. The DTWAIN_RANGE emulates the TWAIN TW_RANGE type. The defined RangeType types are as follows:

Data Type	Value	Definition
DTWAIN_RANGELONG	2	Range will hold LONGs
DTWAIN_RANGEFLOAT	3	Range will hold DTWAIN_FLOATs

The returned DTWAIN_RANGE is valid until DTWAIN_RangeDestroy or DTWAIN_SysDestroy is called. Once the DTWAIN_RANGE is created, the values that define the DTWAIN_RANGE must be set by calling the various DTWAIN_RANGE functions.

TWAIN State Transitions

None.
