I/P n O/P Data passing between the shared object and main application

Hi Guys,

I do have a small query. Suppose I would have to pass two arguments, say, a derived data type(like a enum) as constant 4 i/p n an inbuilt data type(say a string)as non constant 4 o/p to one of my shared obj's function from my main application. What would be the best way to do it? Both the projects r different directories. I searched a lot n got very confused. So I am once again bothering u a bit my dear friends. The code might be looking like this

SharedObjClass.someFunc( const SomeDerivedEnum& ipEnum, std::string& opString )

Now I want to call this function from my main application and want to pass these two variables, i.e., to send the I/P enum in turn to receive the O/P string.

Also is there any safe method to be sure that the .SO has been loaded when in need n got unloaded when it's purposes got over(provided all other factors like lib including, lib search path, etc r taken care of)? For Windows also, how these two problems can be resolved?

I would be very obliged to you people if you can help me regarding this. Thanks in advance!!!
