## ILibAsyncUDPSocket.c

### Abstract
ILibAsyncUDPSocket provides the underyling UDP socket implementation for the Mesh Agent.

### Functions

**ILibAsyncUDPSocket_JoinMulticastGroupV4(module, multicastAddr, localAddr)**  
Joins an IPv4 Multicast group, using the specified interface

**ILibAsyncUDPSocket_JoinMulticastGroupV6(module, multicastAddr, ifIndex)**  
Joins an IPv6 Multicast group, using the specified interface index

**ILibAsyncUDPSocket_DropMulticastGroupV4(module, multicastAddr, localAddr)**  
**ILibAsyncUDPSocket_DropMulticastGroupV6(module, multicastAddr, ifIndex)**  
Leaves the specified multicast group, on the specified interface/index.

**ILibAsyncUDPSocket_SetMulticastInterface(module, localInterface)**  
Sets the local interface to use, when multicasting

**ILibAsyncUDPSocket_SetMulticastTTL(module, TTL)**  
Sets the Multicast TTL value

**ILibAsyncUDPSocket_SetMulticastLoopback(module, loopback)**  
Sets whether or not outbound multicasts are received on the local machine

**ILibAsyncUDPSocket_SetBroadcast(module, enable)**  
Enable/Disable the broadcast flag for the ILibAsyncUDPSocket object

**ILibAsyncUDPSocket_GetPendingBytesToSend(socketModule)**  
Returns the number of bytes that are pending to be sent

**ILibAsyncUDPSocket_GetTotalBytesSent(socketModule)**
