DESCRIPTION

       eio_fdatasync(3) synchronizes a file's in-core state with storage device.

PARAMETERS

	      o $fd
		- Stream, Socket resource, or numeric file descriptor, e.g. returned by eio_open(3).

	      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:

		     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)
