### NAME

util - 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 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>`.
