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