Problem with function call from DLL. Can you help?

Question

C++ / C#

Hello.
I'm trying to call an exported function from a dll, but the program fails. By offsets, I came to the line mov eax,[libssp-0.dll!__stack_chk_guard], where the program ends its work.
Can anyone tell me what is the problem here and how to get rid of it?

Answer 1

Broke the stack. Most likely the function was stdcall, and you called it as cdecl. Or vice versa. The crystal ball refuses to show in more detail.

Answer 2

I export the function as: int __declspec(dllexport) main(int argc, char *argv[]).
I call:
int (*DllFunc)();
h = LoadLibraryA((LPCSTR)"D:\\programms\\MinGW\\msys\\1.0\\tor\\tor-dll\\tor-0.2.4.24\\src\\or\\tor.dll") ;
DllFunc =(int(*) (void)) GetProcAddress(h, (LPCSTR)"main");
Dll Func();
If it helps no more wang :)

Answer 3

You are exporting a function with two arguments, but you are importing with no arguments. It is not right.
