dns_ip4_qualify(3)	   Library Functions Manual	    dns_ip4_qualify(3)

NAME
       dns_ip4_qualify - qualify name and look up IPv4 addresses

SYNTAX
       #include	<libowfat/dns.h>

       int dns_ip4_qualify(stralloc* out,stralloc* fqdn,
			   const stralloc* udn);

DESCRIPTION
       dns_ip4_qualify	feeds  the name	udn through qualification and looks up
       4-byte IP addresses for the result. It puts the fully qualified	domain
       name  into  fqdn,  puts the concatenation of the	IP addresses into out,
       and returns 0. If the domain does not exist in DNS, or has  no  IP  ad-
       dresses,	out will be empty.

       If dns_ip4_qualify has trouble with the qualification, has trouble with
       DNS, or runs out	of memory, it returns -1, setting errno	appropriately.
       It may or may not change	out and	fqdn.

QUALIFICATION
       See http://cr.yp.to/djbdns/qualification.html
