c++ - Buggy call to WSACleanup() kills WSAStartup() -

-

I have an application that is running TCP server to start TCP I WSAStartup () run Then I have to load the third party DLL. DLL also does some TCP jobs and there is some bug in it - it runs WSAStartup () without running WSACleanup () . This bug breaks down my TCP server because DLL's WSACleanup () kills it.

I can not decide dll. How to avoid this situation use the DLL and my TCP server in various threads.

That you can see in, calculating the internal reference, WSAStartup / WSACleanup . So you only have to call WSAStartup twice.

In this way, when your library calls WSACleanup , it will reduce only one internal counting and not release all the resources.

c++ - Redefined variable in the other module -

-
Why do we redefine the variable in other modules, so it is OK to add this module together? I have written two modules main.cpp and module.cpp as the following: // - main.cpp-- // # include & lt; Stdio.h & gt; Int main () {int i = 5; Printf ("I value is% d", i); } and // - module.cpp - // int i = 7; I am now compiling and adding g ++ as the following: g ++ -c main .cpp g ++ - c module. cao g ++ - o bin main.o module.o and it's okay. But I hope the compilation will be successful, while the linker will throw an exception like redefining varaible when I'm running .bin output then the value of i is 5 . UPD: I understand that if we use I as global variable module main.cpp that linker will throw an error. The main variable in the function is a local variable of i function. It is not visible and is present outside the function is. Consider the following example #include & lt; Iostream & gt; Int i = 3; Int main (...
