The primary function of dlltool.exe is to bridge this gap. It looks inside compiled object files ( .o ), archive files ( .a ), or standardized module definition text files ( .def ) to discover which functions are exported. It then automatically creates the structural files needed by the system runtime loader to map the memory references seamlessly. Core Use Cases
