The IG_ISIS_drv_get_version function retrieves the minor version number of an ISIS driver. Currently, this is the number to the right of the decimal point in the version number. For example, if a driver has the version number "1.234", IG_ISIS_drv_get_version will retrieve the minor version number of "234." The major version number for all ISIS drivers is "1." This is the number to the left of the decimal point.
IG_ISIS_drv_get_version can be used to display the version number of the current scanner driver in a scan settings dialog or with some other status reporting mechanism. It should not, however, be used for version comparison during the application installation process to determine whether to install a particular driver. If you are building an installer and needs to check driver versions to determine whether to install a newer driver, you should check the version resources provided by Windows.
