  Unused Parameters
  Submitted by



I like to compile my projects with the highest warning levels, and I often find myself with a number of warnings regarding "unreferenced formal parameters". There are other ways of handling it, but I like this one (at least until someone points out something horrible about it):

template <typename t
inline void dhUnusedParameter(t p_t){
    p_t;
} 



At the beginning of WinMain I can put:

dhUnusedParameter(p_prev_instance); 



Which not only stops the warning, but also clearly documents that the parameter really isn't being used.

Stay Casual,

The zip file viewer built into the Developer Toolbox made use of the zlib library, as well as the zlibdll source additions.
