PROCDESC(4) BSD Kernel Interfaces Manual PROCDESC(4) NAME procdesc -- process descriptor facility SYNOPSIS options PROCDESC 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), wait4(2), pdfork(2), pdgetpid(2), pdkill(2), pdwait4(2), capsicum(4) HISTORY procdesc first appeared in FreeBSD 9.0, and was developed at the Univer- sity 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 August 21, 2013 BSD
