dns_name4(3)		   Library Functions Manual		  dns_name4(3)

NAME
       dns_name4 - look	up host	name

SYNTAX
       #include	<dns.h>

       int dns_name4(stralloc* out,const char* ip[4]);

DESCRIPTION
       dns_name4  looks	up the domain name for the 4-byte IP address in	ip. It
       puts the	(first)	domain name into out and returns 0.  If	 the  relevant
       in-addr.arpa  domain  does not exist in DNS, or has no PTR records, out
       will be empty.

       If dns_name4 has	trouble	with the DNS lookup or runs out	of memory,  it
       returns -1, setting errno appropriately.	It may or may not change out.
