In order to do that, you'll need to use the SCM_RIGHTS and SCM_CREDENTIALS ancillary messages. To access those, you'll need the equivalent of the CMSG_* macros, which are OS/libc dependent. With some gcc -E manual work you should be able to translate those to Lisp, but you need to do it for every ABI you plan to support. See unix(7) and cmsg(3). -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur.
