This function returns the DTWAIN version information in the form of a text string.  The lpszBuffer is the address of the buffer that will be filled in.  If lpszBuffer is NULL or 0, DTWAIN_GetVersionString returns the number of characters needed to store the entire string information plus 1 ( for the NULL terminator character).

 

The lBufSize is the maximum number of characters pointed to by lpszBuffer.  This argument is ignored if lpszBuffer is NULL.
