The net_ip2host function transforms a textual IP address into a fullyqualified domain name and returns the name.
This function works only if the DNS directive is enabled in the magnus.conf file.
char *net_ip2host(char *ip, int verify);
A new string containing the fullyqualified domain name if the transformation is accomplished, or NULL if the transformation is not accomplished.
char *ip is the IP address as a character string in dotted-decimal notation: nnn.nnn.nnn.nnn.
int verify, if nonzero, specifies that the function should verify the fullyqualified domain name. Though this verification requires an extra query, you should use it when checking the access control.
