Support passing string through `ffi.string()` #10

Closed vsergeev closed 3 years ago

vsergeev commented 3 years ago 
local ffi = jit and require('ffi') or require('cffi')

local s = "hello world"
print(ffi.string(s)) --> expected: "hello world", get: bad argument #1 to 'string' (cannot convert 'string' to 'char const *')

LuaJIT FFI allows passing a string argument through ffi.string().
