Decompile Dll -

__declspec(dllexport) void greet(char* name) char buffer[100]; sprintf(buffer, "Hello, %s", name); MessageBoxA(NULL, buffer, "Greeting", MB_OK);

void greet(char *name) char buffer[100]; sprintf(buffer, "Hello, %s", name); MessageBoxA(NULL, buffer, "Greeting", 0);

// export.c __declspec(dllexport) int add(int a, int b) return a + b;

Simple arithmetic decompiles perfectly because it maps directly to ADD instructions.

cl /LD export.c

int add(int a, int b) return a + b;
