.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 .
