EIO_MKNOD(3)								 1							      EIO_MKNOD(3)

eio_mknod - Create a special or ordinary file.

SYNOPSIS
       resource  eio_mknod  (string   $path,  int   $mode, int	$dev, [int  $pri = EIO_PRI_DEFAULT], [callable	$callback = NULL], [mixed  $data =
       NULL])

DESCRIPTION
       eio_mknod(3) creates ordinary or special(often) file.

       Warning

	      This function is currently not documented; only its argument list is available.

PARAMETERS
	      o $path
		- Path for the new node(file).

	      o $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.

	      o $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 spe-
		cial file. Otherwise $dev ignored. See mknod(2) man page for details.

	      o $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.

	      o $callback
		-$callback function is called when the request is done. It should match the following prototype:

	      void callback(mixed $data, int $result[, resource $req]);

		     o $data
		       -is custom data passed to the request.

		     o $result
		       -request-specific result value; basically, the value returned by corresponding system call.

		     o $req
		       -is optional request resource which can be used with functions like eio_get_last_error(3)

	      o $data
		- Arbitrary variable passed to $callback.

RETURN VALUES
       eio_mknod(3) returns request resource on success or FALSE on error.

EXAMPLES
       Example #1

	      eio_mknod(3) 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();
	      ?>
