[C] Winapi Call Dynamically and easily

[mcp]

@0xalloc: I don't understand what problem this solves in the first place? In which cases do you call an API while at the same time not knowing its function signature? I mean, you cannot even correctly call any API without knowing its signature, i.e., how many bytes to push/pop off the stack?

in c/c++ you need to define function prototype first, with this no prototypes are needed.

Right, but you cannot invoke an API without knowing its prototype! So that means you know the prototype already when using the "DynCall" mechanism. So the only thing it saves you is a one-line typedef? But you loose type correctness for all API arguments...that seems like a very bad trade-off.

trade-off is bad or not is subjective to where it is used.

Well, it's pretty uncontroversial that losing type correctness for your API calls *is* bad for overall correctness of your program. The amount of work you're saving is marginal, and at the same time you have to deal with the dangers of type system violations. How is that not a bad trade-off? And we haven't even talked about the loss of readability of DynCall vs regular API calls...
