보드없이 Mil만 사용하고자 할때, 전 위와 같이 사용하고 있습니다.

SHAWN 님이 쓰신 글 :
: 안녕하세요. 요즘 Matrox Mil을 공부하고 있는데요.
:
: 관련 예제코드를 학습하는데 예제코드의 결과값이 안나와서
:
: MappAllocDefault라는 함수를 제거하고
:
: Application, System, Image ID값을 각각 할당 받게해서 바꿔서 했습니다.
:
: 예를들어,
: MappAllocDefault(M_SETUP, &MilApplication, &MilSystem, M_NULL, M_NULL, M_NULL); //이 함수를
:
: MappAlloc(M_SETUP, &MilApplication); //이 두가지
: MsysAlloc(M_DEF_SYSTEM_TYPE, M_DEF_SYSTEM_NUM, M_SETUP, &MilSystem); //함수로
:
: 이랬더니 비록 application id는 0이지만 system id값을 할당 받아서
:
: MbufRestore 이 함수를 호출했습니다. 근데 계속 여기서 access violation이 발생하네요.....(error 이미지 업로드했습니다.)
:
: 이유를 잘 모르겠어서 질문을 올립니다.
:
: 코딩 환경은 XE1에 mil 8.0입니다. 그리고 제가만든 코드와 원본 예제코드를 올리겠습니다.
