       function call.  This application is Name Service Switch aware and  fol‐
       lows the lookup policies in The supported lookup_type values are:

	      Used to resolve host name or IP Address lookups.

	      Used to resolve user name or UID lookups.
			     Assumes  that  a  numeric	value  is a UID.  This
			     option is to be obsoleted.	 Use and instead.

       user name, user ID, group name, or group ID.

       The  lookup_policy  must	 be  a	valid  lookup policy described in nss‐
       witch.conf(4).  If the policy is invalid,  the  system  default	policy
       will be used.  The default values for lookup_policy are:

	      dns [NOTFOUND=return] nis [NOTFOUND=return] files

	      files nis

	      files nis

	      dns [NOTFOUND=return] files

       being queried, and the result of the query.
