kvm - kernel memory interface
This set of functions is defined in the libkvm library.
The kvm(3) functions are used in programs that can request information
transparently either from alive kernel or a dead one. This library is used
in the NetBSD userland programs like ps(1), w(1) or who(1).
Inteceptors for the kvm(3) functions require programs linked with -lkvm,
even if they don't use the features as we leak dlerror(3) for unknown
symbols.
