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.
