Getting rid of multiple function headers?

There has to be a better way to do what I want to do.

I am currently doing this:

-In my Flow.h file I have this -
#if HARDWARETYPE1
      virtual int  SocketReceive(HardwareType1Startup* pHardware1StartupObj);
#elif HARDWARETYPE2
      virtual int  SocketReceive(HardwareType2Startup* pHardware2StartupObj);
#elif HARDWARETYPE3
      virtual int  SocketReceive(HardwareType3Startup* pHardware3StartupObj);
#endif

-So now in my Flow.cpp file I have this-
#if HARDWARETYPE1
int CFlow::SocketReceive(HardwareType1Startup* pHardware1StartupObj)
#elif HARDWARETYPE2
int CFlow::SocketReceive(HardwareType2Startup* pHardware2StartupObj)
#elif HARDWARETYPE3
int CFlow::SocketReceive(HardwareType3Startup* pHardware3StartupObj)
#endif
{
       ....
       ....
}

Is there a better way to combine the function headers so that I don't have 3 different ones depending on what build I am using?

Well, if you have access to the source code for HardwareTypeXStartup, you can create a common base class for all of them and manipulate each Startup object with a pointer to this base class. Or you can also use template to achieve similar effect.

Define three classes derived from CFlow:

CFlowHardwareType1
CFlowHardwareType2
CFlowHardwareType3

Implement SocketReceive in the derived classes.

Only link the derived class that you need in your build.
