MAX SIZE에 구조체의 사이즈를 넣어야 댔는데, 포인터의 사이즈를 넣어버렸군요....
그럼 즐거운 하루 되십시요. *^^*

   FMemoryMap := CreateFileMapping(Dword(-1), nil, PAGE_READWRITE, 0, sizeof(SProcessLogMap), 'Process Log Map - HoPe(V1.0)');

: 안녕하세요.
: C++ Builder를 사용하여 메모리 맵핑 테스트를 완료하였습니다.
: 지금은 델파이로 MapViewOfFile을 사용하여 메모리 맵핑을 하려고 합니다.
:
: 하지만, 동일한 구조체인데 C++에서는 정상적인 주소가 반환이 되고, 델파이에서는 nil이 반환됩니다.
: 혹시 제가 모르는 설정값이 있는지요?
: 여러 고수님들의 고견을 듣겠습니다.
: 수고하십시요.
