C API Reference -- Ns_GetHostByAddr

### Ns_GetHostByAddr

#### Overview

Convert an IP address to a hostname

#### Syntax

        int 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 NS_FALSE; otherwise, it returns NS_TRUE. 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).
