GETHOSTNAME(2)	    UNIX Programmer's Manual	   GETHOSTNAME(2)


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 pro-
     vided.

     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
     bootstrapped.

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.
