"구문 오류 : _stdcall"을 디버그하는 방법?

Question

이 코드를 사용하여 카드 리더와 통신하는 데 필요한 API를 정의하려고합니다. 아래는 헤더 파일 (완료)입니다. [atusbhid.h

몇 가지 오류가 발생하지만 구문 문제가 해결되면 나머지는 제자리에 들어갑니다.

__xport가 __declSpec으로 대체되었으며 원래 VC ++ 6으로 컴파일되었으므로 VS2005를 사용하고 있기 때문에 내가 놓친 것이있을 수 있습니다.

오류 C2059 : 구문 오류 : '__stdcall'

해결 했어, 감사합니다! stdafx.h 파일에 헤더 파일을 포함시키고 사전 컴파일 된 헤더 태그를 설정해야했습니다.

감사!
