Ns_GetHostByAddr

Overview

Convert an IP address to a hostname

Syntax

    char *Ns_GetHostByAddr(
    	Ns_DString *pds,
    	char       *addrStr
    );

Description

The Ns_GetHostByAddr function converts a numeric IP address into a host name. If no name can be found, the function returns NULL. Because the response time of the Domain Name Service can be slow, this function may significantly delay the response to a client. The hostname string is appended to the specified Ns_DString (pds).
