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).

HISTORY

     sity of Cambridge.
