46The
47.Nm
48library is the system utilities library and contains various
49system-dependent utility routines used in a wide variety of system daemons.
50The abstracted functions are mostly related to pseudo-terminals
51and login accounting.
52These routines are
53.Nx Ns -specific
54and are not portable.
55Their use should be restricted.
56Declarations for these functions may be obtained from the include file
57.Pa \*[Lt]util.h\*[Gt] .
