NAME
util, libutil
— system utilities
library
LIBRARY
library “libutil”
DESCRIPTION
Theutil 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
NetBSD-specific and are not portable. Their use should
be restricted.
Declarations for these functions may be obtained from the include
file <util.h>. The
util library and the associated functions are
implemented within the /usr/src/lib/libutil
directory.
