Comments

The DTWAIN_CloseSource function closes the DTWAIN_SOURCE Source. This function should only be called if the application called DTWAIN_OpenSource using Source as the Source to open.

The DTWAIN_CloseSource function will return FALSE if the Source is currently acquiring images. Only when either the acquisitions have completed, or the user-interface is closed is it valid to close a TWAIN Source.
