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.
