C++ MSVC dll compiling error missing type specifier and redefinition
I'm using Microsoft Visual Studio Community 2015 Update 3 and im compiling a dll. I want to call the function InitPreySplitPipe i have already tried calling it with ::pr::InitPreySplitPipe and i copied the interprocess.cpp code into game_local.cpp and interprocess.hpp code into game_local.h and call it from there but that didnt work either.
I have set up a GitHub repository with all the code if some one is interested.
Thanks for reading and sorry for my bad english :/
Compiler output:
Error C4430 missing type specifier - int assumed. Note: C++ does not support default-int
Error C2371 'pr::InitPreySplitPipe': redefinition; different basic types

You are not calling the function from within anything, so the compiler thinks it's a new function declaration. Thus the type int is assumed, of which the overloaded function int pr:InitPreySplitPipe() conflicts with your void pr::InitPreySplitPipe(). This explains all 3 error messages.
