Comments

The DTWAIN_RangeSetAll function sets all of the values that define the DTWAIN_RANGE. The addresses of the values that will be set by DTWAIN_RangeSetAll must be passed, not the actual values. Since DTWAIN_RANGEs can differ in data types, the caller to this function is responsible in seeing that the data residing at the address matches the data type (either DTWAIN_RANGELONG or DTWAIN_RANGEFLOAT).

If the lpDef or lpCur values are NULL, the default (denoted by lpDef) or the current value (denoted by lpCur) is set to 0.

TWAIN State Transitions

None.
