503   * @G_IO_ERROR_CONNECTION_CLOSED: Connection closed by peer. Note that this
504   *     is the same code as %G_IO_ERROR_BROKEN_PIPE; before 2.44 some
505   *     "connection closed" errors returned %G_IO_ERROR_BROKEN_PIPE, but others
506   *     returned %G_IO_ERROR_FAILED. Now they should all return the same

513   * Note that this domain may be extended in future GLib releases. In
514   * general, new error codes either only apply to new APIs, or else
515   * replace %G_IO_ERROR_FAILED in cases that were not explicitly
516   * distinguished before. You should therefore avoid writing code like

525   * #G_IO_ERROR_FAILED.
526   *
527   * See also #GPollableReturn for a cheaper way of returning
528   * %G_IO_ERROR_WOULD_BLOCK to callers without allocating a #GError.
