	          **[in]** **host** - Input hostname

	          **[out]** **canonhost_out** - Canonicalized hostname

This function canonicalizes orig_hostname, possibly using name service lookups if configuration permits. Use :c:func:`krb5_free_string()` to free *canonhost_out* when it is no longer needed.
