Hi, near as i can tell (from tests and code), ptsname and grantpt both require the passed-in fd to exist in /dev/pts. So if you pass in an fd from a newinstance devpts mounted elsewhere things can go wrong. Particularly if the passed-in fd is for /other/dev/pts/0 and /dev/pts/0 does not exist, then grantpt and ptsname will return -ENOENT. The manpage should probably mention that. I've not written anything for it yet. (Willing to, but not until this weekend I'm afraid.) thanks, -serge -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
