++.Os
++.Sh NAME
++.Nm injail
++.Nd determine if a process is running in a jail
++.Sh SYNOPSIS
++.Nm
++.Sh DESCRIPTION
++The
++.Nm
++utility returns a result which indicates the jailed status of
++the current process environment.
++.Sh DIAGNOSTICS
++The
++.Nm
++utility exits with one of the following values:
++.Bl -tag -width indent -compact
++.It 0
++the process is running in a jail.
++.It 1
++the process is not running in a jail.
++.It 2
++an error prevented determining if the process is running in a jail.
++.El
++.Sh BUGS
++.Nm
++uses kvm_getprocs(3) to determine process status. Anything which
++could cause a failure in either kvm_open(3) or kvm_getprocs(3) can
++cause this to fail as well. There aught to be a cleaner way.
