Remarks

The version number that is specified by dwClientVersion and pdwNegotiatedVersion is a composite version number composed of both major and minor versions. The major version is specified by the high-order word and the minor version is specified by the low-order word. The macros WLAN_API_VERSION_MAJOR(_v) and WLAN_API_VERSION_MINOR(_v) return the major and minor version numbers respectively. You can construct a version number by using the macro WLAN_API_MAKE_VERSION(_major, _minor).
