|
|
The
|
|
.Nm
|
|
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
|
|
.Nx Ns -specific
|
|
and are not portable.
|
|
Their use should be restricted.
|
|
Declarations for these functions may be obtained from the include file
