### A `posix_mknod` example

    <?php

    $file = '/tmp/tmpfile';  // file name
    $type = POSIX_S_IFBLK;   // file type
    $permissions = 0777;     // octal
    $major = 1;
    $minor = 8;              // /dev/random

    if (!posix_mknod($file, $type | $permissions, $major, $minor)) {
        die('Error ' . posix_get_last_error() . ': ' . posix_strerror(posix_get_last_error()));
    }

    ?>
