Function webview_create 

pub unsafe extern "C" fn webview_create(
    debug: c_int,
    window: *mut c_void,
) -> webview_t

Creates a new webview instance.

@param debug Enable developer tools if supported by the backend. @param window Optional native window handle, i.e. @c GtkWindow pointer @c NSWindow pointer (Cocoa) or @c HWND (Win32). If non-null, the webview widget is embedded into the given window, and the caller is expected to assume responsibility for the window as well as application lifecycle. If the window handle is null, a new window is created and both the window and application lifecycle are managed by the webview instance. @remark Win32: The function also accepts a pointer to @c HWND (Win32) in the window parameter for backward compatibility. @remark Win32/WebView2: @c CoInitializeEx should be called with @c COINIT_APARTMENTTHREADED before attempting to call this function with an existing window. Omitting this step may cause WebView2 initialization to fail. @return @c NULL on failure. Creation can fail for various reasons such as when required runtime dependencies are missing or when window creation fails. @retval WEBVIEW_ERROR_MISSING_DEPENDENCY May be returned if WebView2 is unavailable on Windows.
