Functions

func CompareBrowserVersions

func CompareBrowserVersions(v1 string, v2 string) (int, error)

CompareBrowserVersions will compare the 2 given versions and return:

   Less than zero: v1 < v2
             zero: v1 == v2
Greater than zero: v1 > v2

func CreateCoreWebView2EnvironmentWithOptions

func CreateCoreWebView2EnvironmentWithOptions(browserExecutableFolder, userDataFolder *uint16, environmentOptions uintptr, environmentCompletedHandle uintptr) (uintptr, error)

CreateCoreWebView2EnvironmentWithOptions tries to load WebviewLoader2 and call the CreateCoreWebView2EnvironmentWithOptions routine.

func GetAvailableCoreWebView2BrowserVersionString

func GetAvailableCoreWebView2BrowserVersionString(path string) (string, error)

GetAvailableCoreWebView2BrowserVersionString returns version of the webview2 runtime. If path is empty, it will try to find installed webview2 is the system. If there is no version installed, a blank string is returned.
