DTWAIN_EnumSourceUnitsEx
|
The DTWAIN_EnumSourceUnitsEx gets all of the current unit of measure supported by the Source.
DTWAIN_ARRAY DTWAIN_EnumSourceUnitsEx ( DTWAIN_SOURCE Source );
Return Values If successful, A DTWAIN_ARRAY of all the units of measures is returned. If there are no Sources or if there is an error, NULL is returned.
Comments The DTWAIN_EnumSourceUnitsEx is the same as DTWAIN_EnumSourceUnits except that the DTWAIN_ARRAY is returned instead of the user having to provide a pointer to a DTWAIN_ARRAY that is filled in with the Sources.
TWAIN State Transitions The Source must be in State 4 or higher.
