`eio_mknod` creates ordinary or special(often) file.

&warn.undocumented.func;
&reftitle.parameters;

`path`

- Path for the new node(file).

`mode`

- Specifies both the permissions to use and the type of node to be created. It should be a combination (using bitwise OR) of one of the file types listed below and the permissions for the new node(e.g. 0640). Possible file types are: `EIO_S_IFREG`(regular file), `EIO_S_IFCHR`(character file), `EIO_S_IFBLK`(block special file), `EIO_S_IFIFO`(FIFO - named pipe) and `EIO_S_IFSOCK`(UNIX domain socket). To specify permissions EIO_S_I* constants could be used.

`dev`

- If the file type is `EIO_S_IFCHR` or `EIO_S_IFBLK` then dev specifies the major and minor numbers of the newly created device special file. Otherwise `dev` ignored. See mknod(2) man page for details.

`pri`

- &eio.request.pri.values;

`callback`

- &eio.callback.proto;

`data`

- Arbitrary variable passed to `callback`.

&reftitle.returnvalues;

`eio_mknod` returns request resource on success,&return.falseforfailure;.

### `eio_mknod` example

    <?php
    // FIFO name
    $temp_filename = "/tmp/eio-temp-fifo";

    /* Is called when eio_mknod() finishes */
    function my_mknod_callback($data, $result) {
        $s = stat($data);
        var_dump($s);

        if ($result == 0) {
            echo "eio_mknod_ok";
        }

        @unlink($data);
    }

    eio_mknod($temp_filename, EIO_S_IFIFO, 0,
        EIO_PRI_DEFAULT, "my_mknod_callback", $temp_filename);
    eio_event_loop();
    ?>
