NAME
       gethostname, sethostname - get/set name of current host

SYNOPSIS
       gethostname(name, namelen)
       char *name;
       int namelen;

       sethostname(name, namelen)
       char *name;
       int namelen;

DESCRIPTION
       Gethostname returns the standard host name for the current processor, as previously set by
       sethostname.  The parameter namelen specifies the size of the name  array.   The  returned
       name is null-terminated unless insufficient space is provided.

       Sethostname  sets the name of the host machine to be name, which has length namelen.  This
       call is restricted to the super-user and is normally used only when the	system	is  boot-
       strapped.

RETURN VALUE
       If  the	call succeeds a value of 0 is returned.  If the call fails, then a value of -1 is
       returned and an error code is placed in the global location errno.

ERRORS
       The following errors may be returned by these calls:

       [EFAULT]       The name or namelen parameter gave an invalid address.

       [EPERM]	      The caller tried to set the hostname and was not the super-user.

SEE ALSO
       gethostid(2)

BUGS
       Host names are limited to MAXHOSTNAMELEN (from <sys/param.h>) characters, currently 64.
