DTWAIN_ArrayGetAtFloatEx

The DTWAIN_ArrayGetAtFloatEx function retrieves a DTWAIN_FLOAT value from a DTWAIN_ARRAY.

DTWAIN_FLOAT DTWAIN_ArrayGetAtFloatEx (

DTWAIN_ARRAY	Array,
LONG	Index );

Parameters

Array

DTWAIN_ARRAY that the value will be retrieved from.

Position

Index of value to retrieve.

Return Values

If successful, the DTWAIN_FLOAT that is located at index Index is returned. If the function fails, returns the minimum finite value representable by a DTWAIN_FLOAT (approximately 2.22507e-308). Call DTWAIN_GetLastError() to get extended information.

Comments

The DTWAIN_ArrayGetAtFloatEx function has the same functionality as DTWAIN_ArrayGetAtFloat, except that the value is returned to the caller instead of the caller providing a pointer to a DTWAIN_FLOAT as a parameter.

TWAIN State Transitions

None.
