UTIL(3)                 NetBSD Library Functions Manual                UTIL(3)


NAME
util, libutil -- system utilities library
LIBRARY
System Utilities Library (libutil, -lutil)
DESCRIPTION
The util library is the system utilities library and contains various system-dependent utility routines used in a wide variety of system dae- mons. 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.
