procdesc — process
descriptor facility
procdesc is a file-descriptor-oriented
interface to process signalling and control, which supplements historic
UNIX fork(2),
kill(2), and wait4(2) primitives with
new system calls such as pdfork(2),
pdkill(2), and pdwait4(2).
procdesc is designed for use with
capsicum(4), replacing process identifiers with
capability-oriented references. However, it can also be used independently
of capsicum(4), displacing PIDs, which may otherwise
suffer from race conditions. Given a process descriptor, it is possible to
query its conventional PID using pdgetpid(2).

procdesc first appeared in
FreeBSD 9.0, and was developed at the University of
Cambridge.
