FMS Connector SDK - How to call server method?

Question

I am using the FMS Connector C++ to do some publishing work. And I am required to call a server side method.

I have tried to use the INetConnection::call() method, but it don't seems successful.

The FMS server spec told me to do,

1.call server method,

nc.call("FCPublish" null, streamname);

2. implement a callback function onFCPublsih

nc.onFCPublish = function (info ) {...}

How can I implement these with FMS Connector C++?

The FMS Connector document include too few topic on calling server side method.

In FMS connector SDK, the netconnection call prototype looks like this,

virtual bool call(const char* funcName, const unsigned char* arguments, unsigned size, OnResultHandler* result) = 0;

thus you will have to serialize the arguments and then pass it to call function.

Check out

bool FMSCTester::testCall(const char* cmd, const char* arg)

method in FMSCTester sample app that comes with SDK on how to serialize and call the function.

For server callbacks, you will have to implement a netconnection sink whose onCommand method will be invoked when server calls a method on client.

The onCommand prototype looks like this,

void onCommand(const char* cmd, const unsigned char* arguments, unsigned bufLen , IRetValue* retVal )

again you can check the MyNCSink class in FMSCTester sample project for an implementation of onCommand.
