JSA里的FFI（2）——宽字符串LPCWSTR

function wstring(s) {

const buff = new ArrayBuffer(s.length * 2 + 2)

const view = new Uint16Array(buff)

for (let i = 0; i < s.length; i++) {

}

return buff

}

function tt()

{

const user32 = FFI.LoadLibrary('User32')

const msgbox = user32.LoadFunction('', 'MessageBoxW', '', 'int32', ['int32', 'pointer', 'pointer', 'int32'])

const wstr = wstring('a😀c')

msgbox.Call(Application.Hwnd, wstr, wstr, 1)
