This structure describes an exception.

Syntax

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

Members

  • ExceptionCode
    Reason the exception occurred. This is the code generated by a hardware exception or the code specified in the RaiseException function for a software-generated exception.

    The following table shows the values likely to occur due to common programming errors.

    Value Description

    EXCEPTION_ACCESS_VIOLATION

    The thread tried to read from or write to a virtual address that it does not have appropriate access to.

    EXCEPTION_ARRAY_BOUNDS_EXCEEDED

    The thread tried to access an array element that is out of bounds and the underlying hardware supports bounds checking.

    EXCEPTION_BREAKPOINT

    A breakpoint was encountered.

    EXCEPTION_DATATYPE_MISALIGNMENT

    The thread tried to read or write data that is misaligned on hardware that does not provide alignment.

    For example, 16-bit values must be aligned on 2-byte boundaries; 32-bit values on 4-byte boundaries, and so on.

    EXCEPTION_FLT_DENORMAL_OPERAND

    An operand in a floating-point operation is too small to represent as a standard floating-point value.

    EXCEPTION_FLT_DIVIDE_BY_ZERO

    The thread tried to divide a floating-point value by a floating-point divisor of zero.

    EXCEPTION_FLT_INEXACT_RESULT

    The result of a floating-point operation cannot be represented exactly as a decimal fraction.

    EXCEPTION_FLT_INVALID_OPERATION

    A floating-point exception not included in this list.

    EXCEPTION_FLT_OVERFLOW

    The exponent of a floating-point operation is greater than the magnitude allowed by the corresponding type.

    EXCEPTION_FLT_STACK_CHECK

    The stack overflowed or underflowed as the result of a floating-point operation.

    EXCEPTION_FLT_UNDERFLOW

    The exponent of a floating-point operation is less than the magnitude allowed by the corresponding type.

    EXCEPTION_ILLEGAL_INSTRUCTION

    The thread tried to execute an invalid instruction.

    EXCEPTION_IN_PAGE_ERROR

    The thread tried to access a page that was not present and the system could not load the page.

    For example, this exception might occur if a network connection is lost while running a program over the network.

    EXCEPTION_INT_DIVIDE_BY_ZERO

    The thread tried to divide an integer value by an integer divisor of zero.

    EXCEPTION_INT_OVERFLOW

    The result of an integer operation caused a carry out of the most significant bit of the result.

    EXCEPTION_INVALID_DISPOSITION

    An exception handler returned an invalid disposition to the exception dispatcher.

    Programmers using a high-level language, such as C, should never encounter this exception.

    EXCEPTION_NONCONTINUABLE_EXCEPTION

    The thread tried to continue execution after a noncontinuable exception occurred.

    EXCEPTION_PRIV_INSTRUCTION

    The thread tried to execute an instruction whose operation is not allowed in the current machine mode.

    EXCEPTION_SINGLE_STEP

    A trace trap or other single-instruction mechanism signaled that one instruction has been executed.

    EXCEPTION_STACK_OVERFLOW

    The thread used up its stack.

    Another exception code is likely to occur when debugging console processes. It does not arise because of a programming error.

    The DBG_CONTROL_C exception code occurs when CTRL+C is input to a console process that handles CTRL+C signals and is being debugged.

    This exception code is not meant to be handled by applications. It is raised only for the benefit of the debugger, and is raised only when a debugger is attached to the console process.

  • ExceptionFlags
    Exception flags. This member can be either zero, indicating a continuable exception, or EXCEPTION_NONCONTINUABLE, indicating a noncontinuable exception.

    An attempt to continue execution after a noncontinuable exception causes the EXCEPTION_NONCONTINUABLE_EXCEPTION exception.

  • ExceptionRecord
    Pointer to an associated EXCEPTION_RECORD structure. Exception records can be chained together to provide additional information when nested exceptions occur.
  • ExceptionAddress
    Address at which the exception occurred.
  • NumberParameters
    Number of parameters associated with the exception. This is the number of defined elements in the ExceptionInformation array.

  • ExceptionInformation
    Array of additional 32-bit arguments that describe the exception. The RaiseException function can specify this array of arguments. For most exception codes, the array elements are undefined.

    The EXCEPTION_ACCESS_VIOLATION exception code specifies that the first element of the array contains a read/write flag which indicates the type of operation that caused the access violation.

    If this value is zero, the thread attempted to read the inaccessible data.

    If this value is 1, the thread attempted to write to an inaccessible address.

    The second array element specifies the virtual address of the inaccessible data.
