Comments This function returns the full DTWAIN DLL version resource 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_GetVersionInfo returns the number of characters needed to store the entire string information plus 1 ( for the NULL terminator character).
The lBufSize is the maximum size, in characters, of the buffer pointed to by lpszBuffer. This argument is ignored if lpszBuffer is NULL.
This function differs from DTWAIN_GetVersionString in that the entire version resource information is included when using DTWAIN_GetVersionInfo, instead of just the version number when you call DTWAIN_GetVersionString.
