.Nm util
.Nd system utilities library
.Sh LIBRARY
.Lb libutil
.Sh DESCRIPTION
The
.Nm
library is the system utilities library and contains various
system-dependent utility routines used in a wide variety of system daemons.
The abstracted functions are mostly related to pseudo-terminals
and login accounting.
These routines are
.Nx Ns -specific
and are not portable.
Their use should be restricted.
Declarations for these functions may be obtained from the include file
.Pa \*[Lt]util.h\*[Gt] .
