EXCEPTION_RECORD Structure

The EXCEPTION_RECORD structure contains information about a hardware exception or a software exception that occurred during the execution of a process.

typedef struct _EXCEPTION_RECORD {
    DWORD ExceptionCode;
    DWORD ExceptionFlags;
    struct _EXCEPTION_RECORD *ExceptionRecord;
    PVOID ExceptionAddress;
    DWORD NumberParameters;
    ULONG_PTR ExceptionInformation[EXCEPTION_MAXIMUM_PARAMETERS];
} EXCEPTION_RECORD, *PEXCEPTION_RECORD;

Members

• ExceptionCode (DWORD)
  The exception code. This member can be an operating-system-defined exception code or an application-defined exception code.
• ExceptionFlags (DWORD)
  Indicates whether the exception is continuable. This member is set to 0 if the exception is not continuable or 1 if it is.
• ExceptionRecord (struct _EXCEPTION_RECORD *)
  A pointer to a nested exception record. If the exception is nested, this member is set to the address of the previous exception record.
• ExceptionAddress (PVOID)
  The address at which the exception occurred.
• NumberParameters (DWORD)
  The number of parameters for the exception. This member can be 0, 1, 3, or 4.
• ExceptionInformation (ULONG_PTR ExceptionInformation[EXCEPTION_MAXIMUM_PARAMETERS])
  An array of parameters for the exception. The number of valid parameters is specified by the NumberParameters member.

Remarks

When an exception occurs, the operating system creates an EXCEPTION_RECORD structure to describe the exception. This structure is passed to the exception dispatcher, which attempts to find a handler for the exception.
