    eio_nop — Does nothing, except go through the whole request cycle

    Açıklama

    eio_nop(int $pri = EIO_PRI_DEFAULT, callable $callback = NULL, mixed $data = NULL): resource

    eio_nop() does nothing, except go through the whole request cycle. Could be useful in debugging.

    Bağımsız Değişkenler

    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.

    Dönen Değerler

    eio_nop() returns request resource on success, başarısızlık durumunda false döner.
