Working with the Transport Layer 301

Connection API

Sample Code

The following sample code demonstrates how to create an application

connection. The application becomes the connection owner and supplies the

connection with its event handlers. In this example, the application chooses to

function.

/*=========================================================================================*/

static RvStatus AppCreateAndInitConnection1(

IN RvSipTransportMgrHandle hTransportMgr,

OUT RvSipTransportConnectionHandle *phConn)

{

RvStatus rv;

RvSipTransportConnectionCfg connCfg;

RvSipTransportConnectionEvHandlers evHandlers;

/*Initializes the event handler structure.*/

memset(&evHandlers,0,sizeof(evHandlers));

evHandlers.pfnConnStateChangedEvHandler = AppConnStateChangedEv;

/*Creates a connection object and supplies the event handlers. In this sample, the

owner is set to NULL.*/

rv = RvSipTransportMgrCreateConnection(hTransportMgr, NULL, &evHandlers,

sizeof(evHandlers), phConn);

if(rv != RV_OK)

{

printf("Failed to create a connection object");

return rv;

}

/*Initializes the configuration structure. Setting the local address is optional.*/

memset(&connCfg,0,sizeof(RvSipTransportConnectionCfg));

connCfg.eTransportType = RVSIP_TRANSPORT_TCP;

connCfg.strDestIp = "172.20.1.1";

connCfg.destPort = 5060;

rv = RvSipTransportConnectionInit (*phConn,&connCfg,sizeof(connCfg));

if(rv != RV_OK)

{

printf("Failed to initialize the a connection object");

return rv;
