Comments

The DTWAIN_RangeGetAllFloatString does exactly the same thing as DTWAIN_RangeGetAllFloat function, with the difference being that the parameters are string buffers instead of pointers to DTWAIN_FLOAT.

This function can be used by computer languages that do not handle 64-bit IEEE parameters correctly. The string buffers (if they are not NULL) must be sized to at least 255 characters.

TWAIN State Transitions

None.
