Nd system utilities library
Sh LIBRARY
Lb libutil
Sh DESCRIPTION
The
Nm
library is the system utilities library and contains various

The abstracted functions are mostly related to pseudo-terminals
and login accounting.
These routines are
Nx Ns -specific
and are not portable.
Their use should be restricted.
Pp
Declarations for these functions may be obtained from the include file
In util.h .
The
Nm
library and the associated functions are implemented within the
Pa /usr/src/lib/libutil
directory.
