.Ft struct cpu_info *
.Fn curcpu "void"
.Ft struct proc *
.Fn curproc "void"
.Ft struct lwp *

The following macros can be used to retrieve
the current processor, process, and light-weight process
.Pq Tn LWP ,
respectively:
.Bl -enum -offset indent
.It
The machine-dependent

.Em cpu_info
structure containing information of the
