Describes an exception.描述异常的结构体

## Syntax ##

C++

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**

The reason the exception occurred. 产生异常的原因。This is the code generated by a hardware exception, or the code specified in the[**RaiseException**][RaiseException] function for a software-generated exception. 这是一个硬件异常产生的代码或者由RaiseException函数指定产生的软件异常码。The following tables describes the exception codes that are likely to occur due to common programming errors.

Another exception code is likely to occur when debugging console processes.其他的异常在调试控制台程序的时候可能发生。 It does not arise because of a programming error. 因为编程的错误可能不会发生。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. **DBG\_CONTROL\_C**异常码在调试控制台程序时输入CTRL+C来处理CTRL+C信号的时候发生。This exception code is not meant to be handled by applications. 这个异常码并不会被应用程序处理。It is raised only for the benefit of the debugger, and is raised only when a debugger is attached to the console process.它的产生只是更好的为调试器服务，也只在调试器附加到控制台程序的时候发生。

**ExceptionFlags**

The exception flags.异常标志。 This member can be either zero, indicating a continuable exception, or**EXCEPTION\_NONCONTINUABLE** indicating a noncontinuable exception.这个参数可以是0，表示可继续执行的异常，也可以是**EXCEPTION\_NONCONTINUABLE**表示不可继续执行的异常。 Any attempt to continue execution after a noncontinuable exception causes the**EXCEPTION\_NONCONTINUABLE\_EXCEPTION**exception.任何试图在不可继续执行的异常发生后继续执行会产生**EXCEPTION\_NONCONTINUABLE\_EXCEPTION**异常。

**ExceptionRecord**

A pointer to an associated **EXCEPTION\_RECORD** structure. 指向**EXCEPTION\_RECORD**结构体的指针。Exception records can be chained together to provide additional information when nested exceptions occur.当嵌套异常发生的时候，异常记录可以形成一个链来提供额外的信息。

**ExceptionAddress**

The address where the exception occurred.异常发生的地址。

**NumberParameters**

The number of parameters associated with the exception. 与异常相关的参数个数。This is the number of defined elements in the**ExceptionInformation** array.这是the**ExceptionInformation**数组的元素个数。

**ExceptionInformation**

An array of additional arguments that describe the exception. 用于描述异常的附加参数的数组。The[**RaiseException**][RaiseException] function can specify this array of arguments. RaiseException函数可以指定这个参数数组。For most exception codes, the array elements are undefined. 对大多数异常码而言，这个数组元素是未定义的。The following table describes the exception codes whose array elements are defined.下面的表格展示了哪些异常码的数组元素是定义了的。

<table> 
 <tbody> 
 <tr> 
 <th>Exception code</th> 
 <th>Meaning</th> 
 </tr> 
 <tr> 
 <td> 
 <dl> 
 EXCEPTION_ACCESS_VIOLATION 
 </dl> </td> 
 <td> The first element of the array contains a read-write flag that indicates the type of operation that caused the access violation. 数组的第一个元素包含了一个读写标志，表示引起访问违规的操作类型。If this value is zero, the thread attempted to read the inaccessible data. 如果这个值为0，表示线程试图读取不可访问的数据。If this value is 1, the thread attempted to write to an inaccessible address. 如果这个值为1，表示线程试图写入不可访问的地址。If this value is 8, the thread causes a user-mode data execution prevention (DEP) violation.如果这个值是8，表示线程线程引发了一个用户模式的DEP违规。 The second array element specifies the virtual address of the inaccessible data.数组的第二个元素指定了不可访问数据的虚拟地址。 </td> 
 </tr>

## Remarks ##

To enable a debugger to debug a target that is running on a different architecture (32-bit versus 64-bit), use one of the explicit forms of this structure.
