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 addresses, 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
