!uniqstack

!uniqstack扩展命令显示当前进程中所有线程的调用堆栈，除开重复的那些。

语法

!uniqstack [ b | v | p ] [ n ]

参数

b

显示中包含传递给每个函数的前3个参数。

v

显示帧指针省略信息(frame pointer omission (FPO) information)。在x86处理器上，还会显示调用约定的信息。

p

显示调用堆栈中每个函数的完整参数。会列出每个参数的数据类型、名字和值。需要完整符号信息。

n

显示帧序号(frame number)。

DLL

注释

除了不显示重复的调用堆栈之外，该命令和k, kb, kd, kp, kP, kv (Display Stack Backtrace)命令类似。
