eio_fchown — Change file ownership

### Description

eio_fchown(
mixed `$fd`,
int `$uid`,
int `$gid` = -1,
int `$pri` = EIO_PRI_DEFAULT,
callable `$callback` = NULL,
mixed `$data` = NULL
): resource

eio_fchown() changes ownership of the file specified by `fd` file descriptor.

### Parameters

`fd`
  Stream, Socket resource, or numeric file descriptor.
`uid`
  User ID. Is ignored when equal to -1.
`gid`
  Group ID. Is ignored when equal to -1.
`pri`

  The request priority: `EIO_PRI_DEFAULT`, `EIO_PRI_MIN`, `EIO_PRI_MAX`, or `null`. If `null` passed, `pri` internally is set to `EIO_PRI_DEFAULT`.

`callback`

  `callback` function is called when the request is done. It should match the following prototype:

  `void callback(mixed $data, int $result[, resource $req]);`
  `data`

    is custom data passed to the request.

  `result`

    request-specific result value; basically, the value returned by corresponding system call.

  `req`

    is optional request resource which can be used with functions like eio_get_last_error().

`data`
  Arbitrary variable passed to `callback`.

### Return Values

eio_chmod() returns request resource on success, or `false` on failure.
