    eio_stat — Get file status

    설명

    resource eio_stat ( string $path , int $pri , callable $callback [, mixed $data = NULL ] )

    eio_stat() returns file status information in result argument of callback

    인수

    path

    The file path

    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.

    반환값

    eio_stat() returns request resource on success or FALSE on error. On success assigns result argument of callback to an array.
