procdesc
PROCDESC(4) BSD Kernel Interfaces Manual PROCDESC(4) NAME
procdesc -- process descriptor facility DESCRIPTION
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). SEE ALSO
fork(2), kill(2), pdfork(2), pdgetpid(2), pdkill(2), pdwait4(2), wait4(2), capsicum(4) HISTORY
procdesc first appeared in FreeBSD 9.0, and was developed at the University of Cambridge. AUTHORS
procdesc was developed by Robert Watson <rwatson@FreeBSD.org> and Jonathan Anderson <jonathan@FreeBSD.org> at the University of Cambridge, and Ben Laurie <benl@FreeBSD.org> and Kris Kennaway <kris@FreeBSD.org> at Google, Inc. BUGS
procdesc is considered experimental in FreeBSD. BSD
