    eio_write — Write to file

    Description

    eio_write(
        mixed $fd,
        string $str,
        int $length = 0,
        int $offset = 0,
        int $pri = EIO_PRI_DEFAULT,
        callable $callback = NULL,
        mixed $data = NULL
    ): resource

    eio_write() writes up to length bytes from str at offset offset from the beginning of the file.

    Parameters

    fd

    Stream, Socket resource, or numeric file descriptor, e.g. returned by eio_open()

    str

    Source string

    length

    Maximum number of bytes to write.

    offset

    Offset from the beginning of file.

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