c++ - Error: expected constructor, destructor, or type conversion before '(' token 2 -

-

i see common error, didn't see response quite fit. trying compile simple c++ application using dec-c++ under win 10. code included chinese usb i/o module, , need recompile prompts , comments in english. first part easy, google translate, project won't compile, giving subject error.

the errors output when compiling included function called main.cpp. offending function below.

i sure appreciate here!

_declspec old spelling of microsoft extension __declspec. telling linker symbols imported library. compiler doesn't appear support it. can either edit source remove it, or add define (#define _declspec(x)) either in code or on command line remove it.
