Gio.Socket.new_from_fd
Description: Reference for Gio.Socket.new_from_fd

### Constructor

# Gio Socketnew_from_fd

since: 2.22

#### Declaration [src]

    GSocket*
    g_socket_new_from_fd (
      gint fd,
      GError** error
    )

#### Description [src]

Creates a new `GSocket` from a native file descriptor or winsock SOCKET handle.

This reads all the settings from the file descriptor so that all properties should work. Note that the file descriptor will be set to non-blocking mode, independent on the blocking mode of the `GSocket`.

On success, the returned `GSocket` takes ownership of `fd`. On failure, the caller must close `fd` themselves.

Since GLib 2.46, it is no longer a fatal error to call this on a non-socket descriptor. Instead, a GError will be set with code `G_IO_ERROR_FAILED`.

Available since: 2.22

#### Parameters

`fd`

  Type: `gint`

  A native socket file descriptor.

`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: `GSocket`

A `GSocket` or `NULL` on error. Free the returned object with g_object_unref().

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