草帽姐歌曲大全:Windows下的异常码（Exception Code）

上午我查一个异常码（0xc000000d）表示的具体含义，我记得以前的确看到过这样一个表格，可查来查去，就是没找着地方。在网上也找了一些资料，但都不是我想要的，都是很笼统地介绍它与内存相关，没有找到类似0xc0000005对应ACCESS_VIOLATION，0xc0000094对应DIVIDE_BY_ZERO这样精确的信息。

晚上看书的时候，通过函数GetExceptionCode终于找到我曾经看到过的那个表格，下面是MSDN中介绍GetExceptionCode的页面上对Exception Code的描述：

Return valueDescriptionEXCEPTION_ACCESS_VIOLATIONThe thread attempted to read from or write to a virtual address that it does not have appropriate access to.EXCEPTION_BREAKPOINTA breakpoint was encountered.EXCEPTION_DATATYPE_MISALIGNMENTThe thread attempted 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_SINGLE_STEPA trace trap or other single-instruction mechanism signaled that one instruction has been executed.EXCEPTION_ARRAY_BOUNDS_EXCEEDEDThe thread attempted to access an array element that is out of bounds, and the underlying hardware supports bounds checking.EXCEPTION_FLT_DENORMAL_OPERANDAn operand in a floating-point operation is denormal. A denormal value is one that is too small to represent as a standard floating-point value.EXCEPTION_FLT_DIVIDE_BY_ZEROThe thread attempted to divide a floating-point value by a floating-point divisor of zero.EXCEPTION_FLT_INEXACT_RESULTThe result of a floating-point operation cannot be represented exactly as a decimal fraction.EXCEPTION_FLT_INVALID_OPERATIONThis exception represents a floating-point exception not included in this list.EXCEPTION_FLT_OVERFLOWThe exponent of a floating-point operation is greater than the magnitude allowed by the corresponding type.EXCEPTION_FLT_STACK_CHECKThe stack overflowed or underflowed as a result of a floating-point operation.EXCEPTION_FLT_UNDERFLOWThe exponent of a floating-point operation is less than the magnitude allowed by the corresponding type.EXCEPTION_INT_DIVIDE_BY_ZEROThe thread attempted to divide an integer value by an integer divisor of zero.EXCEPTION_INT_OVERFLOWThe result of an integer operation caused a carry out of the most significant bit of the result.EXCEPTION_PRIV_INSTRUCTIONThe thread attempted to execute an instruction whose operation is not allowed in the current machine mode.EXCEPTION_NONCONTINUABLE_EXCEPTION

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

遗憾的是，始终没有发现0xc000000d的踪迹。

我就不信了……

终于让我找到了！

在翻看Windbg的帮助文件，查0xc0000005相关的信息时，有一节“Bug Check 0x1E: KMODE_EXCEPTION_NOT_HANDLED”中提到了一个NTStatus.h的文件，通过计算机搜索，竟然与WinNT.h相同的路径，即，Microsoft Visual Studio 8\VC\PlatformSDK\Include\NTStatus.h，里面规定了0xc000000d的意义：

// MessageId: STATUS_INVALID_PARAMETER
// MessageText:
//  An invalid parameter was passed to a service or function.
#define STATUS_INVALID_PARAMETER         ((NTSTATUS)0xC000000DL)

此外，这个文件中还规定了其它错误码的具体含义，而且从0x00000000L~0xC01A002EL，大部分都是连续的定义，非常全，感觉这个地方才是“源头”。

真没想到，我苦苦追求的答案竟然与已经找到的结果“近在咫尺”，真有点“众里寻他千百度，蓦然回首，那人却在灯火阑珊处”的味道。
