GetExceptionInformation

When an exception occurs, the operating system pushes the following three structures on the stack of the thread that raised the exception: the EXCEPTION_RECORD structure, the CONTEXT structure, and the EXCEPTION_POINTERS structure.

The EXCEPTION_RECORD structure contains CPU-independent information about the raised exception, and the CONTEXT structure contains CPU-dependent information about the raised exception. The EXCEPTION_POINTERS structure has only two data members that are pointers to the pushed EXCEPTION_RECORD and CONTEXT data structures:

typedef struct _EXCEPTION_POINTERS {
   PEXCEPTION_RECORD ExceptionRecord;
   PCONTEXT ContextRecord;
} EXCEPTION_POINTERS, *PEXCEPTION_POINTERS;
