Comments

The DTWAIN_GetOCRManufacturer function fills szBuffer with the manufacturer associated with the OCR engine Engine. The MaxLen argument is the maximum number of characters to copy to szBuffer, including the trailing null character.

 

If szBuffer is NULL, the length of the manufacturer's name is returned only.  The returned length includes the length of the name, plus one for the terminating NULL character.  You can use this method to determine the total number of characters needed to store the entire name.
