free : the handle is invalid about node-vlc

[skiqh]

Same error message for me on win7-x86.

d:\vlc\node_modules\vlc\node_modules\ffi\lib\dynamic_library.js:112
    throw new Error('Dynamic Symbol Retrieval Error: ' + this.error())
          ^
Error: Dynamic Symbol Retrieval Error: "free": The handle is invalid.

libvlc.dll is in C:\Program Files\VideoLAN\VLC (version 2.1.2)

Workaround for Windows.

var libc = ffi.Library('msvcrt', {
  'free': ['void', [ 'pointer' ]],
});
