背景
因为要批量分析dump文件。发现可以使用windbg来批量分析dump文件。
如何调用
网络上有很多关于windbg的介绍，但是却很少介绍cdbg，就是windbg的命令行模式 。
常用命令：
cdbg -help的方法
-z dump_path dump路径
-y pdbpath pdb路径
还有更多的详细的命令可以查看 -help
如果你有符号服务器那么你可以设置 环境变量。
常用环境变量
_NT_ALT_SYMBOL_PATH=[Drive:][Path]
Specify an alternate symbol image path.
_NT_ALT_SYMBOL_PATH=[Drive:][Path]
Specify an alternate symbol image path.
第一个可以设置远程共享符号器
环境名：_NT_SYMBOL_PATH
环境值： SRV* \192.168.7.4\symbols_release*http://msdl.microsoft.com/download/symbols
本地备份变量：
环境名：_NT_ALT_SYMBOL_PATH
环境值：cache*F:\Temp\symbols;\symbols_server\ReleaseSymbols;\symbols_server\TempSymbols;\symbols_server\WinSymbols
这样就可以了
下面这几个路径，可以看说明：
_NT_SYMBOL_PATH=[Drive:][Path]
Specify symbol image path.
_NT_ALT_SYMBOL_PATH=[Drive:][Path]
Specify an alternate symbol image path.
_NT_DEBUGGER_EXTENSION_PATH=[Drive:][Path]
Specify a path which should be searched first for extensions dlls
_NT_EXECUTABLE_IMAGE_PATH=[Drive:][Path]
Specify executable image path.
_NT_SOURCE_PATH=[Drive:][Path]
Specify source file path.
_NT_DEBUG_LOG_FILE_OPEN=filename
If specified, all output will be written to this file from offset 0.
_NT_DEBUG_LOG_FILE_APPEND=filename
If specified, all output will be APPENDed to this file.
_NT_DEBUG_HISTORY_SIZE=size
Specifies the size of a server's output history in kilobytes

-d sends all debugger output to kernel debugger via DbgPrint
input is requested from the kernel debugger via DbgPrompt
-d cannot be used with debugger remoting

input is requested from the kernel debugger via DbgPrompt unless
there are remote clients that can provide input
-ddefer can only be used when the kernel debugger is enabled
-ddefer should be used with -server
-ee <name> set default expression evaluator
<name> can be MASM or C++
-failinc causes incomplete symbol and module loads to fail

This only works on Windows XP and later

fault (see _NT_EXECUTABLE_IMAGE_PATH)

during CreateProcess

-lines requests that line number information be used if present
-loga <logfile> appends to a log file
-logau <logfile> appends to an Unicode log file
-logo <logfile> opens a new log file
-logou <logfile> opens a new Unicode log file
-myob ignores version mismatches in DBGHELP.DLL
-n enables verbose output from symbol handler

-o debugs all processes launched by debuggee
-p <pid> specifies the decimal process ID to attach to
-pb specifies that the debugger should not break in at attach

-pn <name> specifies the name of the process to attach to
-pr specifies that the debugger should resume on attach
-psn <name> specifies the process to attach to by service name
-premote <transport>:server=<name>,<params>
specifies the process server to connect to
transport arguments are given as with remoting
-pt <#> specifies the interrupt timeout
-pv specifies that any attach should be noninvasive
-pvr specifies that any attach should be noninvasive and nonsuspending
-QR \\<machine> queries for remote servers
-r <BreakErrorLevel> specifies the (0-3) error level to break on (see
SetErrorLevel)
-remote <transport>:server=<name>,<params>
lets you connect to a debugger session started with -server
must be the first argument if present
transport: tcp | npipe | ssl | spipe | 1394 | com

for tcp use: port=<socket port #>
for npipe use: pipe=<name of pipe>
for 1394 use: channel=<channel #>
for com use: port=<COM port>,baud=<baud rate>,
