/* * readdir returns directory entries from ptyfsnode (vp). * * the strategy here with ptyfs is to generate a single * directory entry at a time (struct dirent) and then * copy that out to userland using uiomove. a more efficent * though more complex implementation, would try to minimize * the number of calls to uiomove(). for ptyfs, this is * hardly worth the added code complexity. * * this should just be done through read() */
