Description: Reference for Meta.WaylandClient.new_subprocess

### Constructor

# Meta WaylandClientnew_subprocess

#### Declaration [src]

    MetaWaylandClient*
    meta_wayland_client_new_subprocess (
      MetaContext* context,
      GSubprocessLauncher* launcher,
      const char* const* argv,
      GError** error
    )

#### Description [src]

Creates a new `MetaWaylandClient`. The `GSubprocesslauncher` and array of arguments are used to launch a new process with the binary specified in the first element of argv, and with the rest of elements as parameters. It also sets up a new Wayland socket and sets the environment variable WAYLAND_SOCKET to make the new process to use it.

#### Parameters

`context`

  Type: `MetaContext`

  A `MetaContext`.

  The data is owned by the caller of the function.

`launcher`

  Type: `GSubprocessLauncher`

  A GSubprocessLauncher to use to launch the subprocess.

  The data is owned by the caller of the function.

`argv`

  Type: An array of `filename`

  Command line arguments.

  The array must be `NULL`-terminated.
  The data is owned by the caller of the function.
  Each element is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the constructor if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `MetaWaylandClient`

A `MetaWaylandClient` or `NULL` if %error is set. Free with g_object_unref().

The caller of the function takes ownership of the data, and is responsible for freeing it.
