Notes: The user termination routine is responsible for returning to the CauseWay termination routines to allow proper shutdown of the application. The instruction must be the proper 16- or 32-bit return to match the CL register setting. For ease of use with high-level languages (specifically Watcom C and setting SS back to DGROUP), [E]SI equals the internal DOS extender stack ESP immediately prior to the 32- or 16-bit call to the termination routine. If an information dump buffer address is provided, register and other termination values are placed into it using the following format:

dword EBP;

dword EDI;

dword ESI;

dword EDX;

dword ECX;

dword EBX;

dword EAX;

dword GS;

dword FS;

dword ES;

dword DS;

dword EIP;

dword CS;

dword EFLAGS;

dword ESP;

dword SS;

word TR;

dword CR0;

dword CR2;

dword CR3;

dword csAddress;

dword dsAddress;

dword esAddress;

dword fsAddress;

dword gsAddress;

dword ssAddress;

word ExceptionNumber;

dword ErrorCode;
