NAME
procdesc —
process descriptor facility
DESCRIPTION
procdesc is a file-descriptor-oriented interface to
process signalling and control, which supplements historic
UNIX
fork(2) and
kill(2),
primitives with new system calls such as
pdfork(2)
and
pdkill(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).
SEE ALSO
fork(2), kill(2), pdfork(2), pdgetpid(2), pdkill(2), kqueue(2), wait4(2), capsicum(4)HISTORY
procdesc first appeared in FreeBSD
9.0, and was developed at the University of Cambridge.
