DTWAIN_RangeGetAllFloat

The DTWAIN_RangeGetAllFloat function gets the low, high, step, default, and current values in the DTWAIN_RANGE.

DTWAIN_BOOL DTWAIN_RangeGetAllFloat (

DTWAIN_RANGE	Range,
LPDTWAIN_FLOAT	lpMin
LPDTWAIN_FLOAT	lpMax
LPDTWAIN_FLOAT	lpStep
LPDTWAIN_FLOAT	lpDef
LPDTWAIN_FLOAT	lpCur );

Parameters

Range

A valid DTWAIN_RANGE type.

lpMin

Address of Minimum value or NULL

lpMax

Address of Maximum value or NULL

lpStep

Address of Step value or NULL

lpDef

Address of default value or NULL

lpCur

Address of current value or NULL

Return Values

TRUE if successful, FALSE otherwise. If the function returns FALSE, call DTWAIN_GetLastError() to get extended information.

Comments

The DTWAIN_RangeGetAllFloat function is a specialization of the DTWAIN_RangeGetAll function, with the difference being that the parameters are pointers to DTWAIN_FLOAT types instead of LPVOID.

If Range stores floating point types, DTWAIN_RangeGetAllFloat will return the value as floating point types. The Range must have been created with the DTWAIN_RANGEFLOAT type.

TWAIN State Transitions

None.
