UTIL(3) Library Functions Manual UTIL(3)

NAME

util, libutilsystem 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 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.
