The 32-bit +identifier is intended to be unique among all UNIX systems in +existence. This normally resembles the Internet address for the local +machine, as returned by +.BR gethostbyname (3), +and thus usually never needs to be set. + +The +.B sethostid +call is restricted to the superuser. + +The +.I hostid +argument is stored in the file +.IR /etc/hostid . +.SH "RETURN VALUE" +.B gethostid +returns the 32-bit identifier for the current host as set by +.BR sethostid (2). +.SH "CONFORMING TO" +4.2BSD. These functions were dropped in 4.4BSD. +POSIX.1 does not define these functions, but ISO/IEC 9945-1:1990 mentions +them in B.4.4.1.
