sethostid - Set the unique identifier of the current host
int sethostid(
int host_id );

The sethostid() function allows a calling process with a
root user ID to set a new 32-bit identifier for the current
host. The sethostid() function enables an application
program to reset the host ID. The host ID is a unique
number that may be used by application programs. It is
usually set to the primary Internet address of the local
machine, represented as a network standard byte order
integer.
The sethostid() function fails if the calling process does
not have the superuser privilege.
Upon successful completion, the sethostid() function
returns a value of 0 (zero). If the sethostid() function
fails, a value of -1 is returned and errno is set to indicate
the error.
If the sethostid() function fails, errno may be set to the
following value: The calling process does not have the
appropriate privilege.
