# ost\_IPV6Multicast(3)

A specialization of IPV6Address that provides address validation for multicast addresses.

## NAME

ost::IPV6Multicast - A specialization of **IPV6Address** that provides address validation for multicast addresses.

## SYNOPSIS

`#include <address.h>`

Inherits **ost::IPV6Address**.

### Public Member Functions

**IPV6Multicast** ()\
 Create an Internet Multicast Address object with an empty (0.0.0.0) address.  **IPV6Multicast** (const struct in6\_addr address)\
 Convert the system internet address data type (struct in\_addr) into a Common C++ **IPV4Multicast** object.  **IPV6Multicast** (const char \*address)\
 Convert a null terminated ASCII multicast address string (example: '224.0.0.1') or multicast name string (example: 'sap.mcast.net') directly into a Common C++ **IPV6Multicast** object.

### Additional Inherited Members

## Detailed Description

A specialization of **IPV6Address** that provides address validation for multicast addresses.

Whenever its value changes the new value is checked to be in the range from 224.0.0.1 through 239.255.255.255. If it is not, an exception is thrown.

## Constructor & Destructor Documentation

### ost::IPV6Multicast::IPV6Multicast ()

Create an Internet Multicast Address object with an empty (0.0.0.0) address.

### ost::IPV6Multicast::IPV6Multicast (const struct in6\_addr address)

Convert the system internet address data type (struct in\_addr) into a Common C++ **IPV4Multicast** object.

**Parameters**

*address* struct of system used binary internet address.

### ost::IPV6Multicast::IPV6Multicast (const char \* address)

Convert a null terminated ASCII multicast address string (example: '224.0.0.1') or multicast name string (example: 'sap.mcast.net') directly into a Common C++ **IPV6Multicast** object. Works like **IPV6Address**(const char\*).

**Parameters**

*address* null terminated C string.
