Pseudo Registers

Pseudoregister	Description
@ERR	Last error value; the same value returned by the GetLastError() API function
@TIB	Thread information block for the current thread; necessary because the debugger doesn't handle the "FS:0" format
@CLK	Undocumented clock register; usable only in the Watch window
@EAX, @EBX, @ECX, @EDX, @ESI, @EDI, @EIP, @ESP, @EBP, @EFL	Intel CPU registers
@CS, @DS, @ES, @SS, @FS, @GS	Intel CPU segment registers
@ST0, @ST1, @ST2, @ST3, @ST4, @ST5, @ST6, @ST7	Intel CPU floating-point registers

@ERR
最后错误值; 和GetLastError() API 函数一致

@TIB
当前线程信息; 在调试器无法处理”FS:0”格式的时候是必要的

@CLK
未列入文档的时钟寄存器; 只是在Watch窗口适用

@EAX, @EBX, @ECX, @EDX, @ESI, @EDI, @EIP, @ESP, @EBP, @EFL
Intel CPU 寄存器

@CS, @DS, @ES, @SS, @FS, @GS
Intel CPU 段寄存器

@ST0, @ST1, @ST2, @ST3, @ST4, @ST5, @ST6, @ST7
Intel CPU 浮点寄存器

其中@TIB很有用,可以用在多线程调试的时候作为断点的条件变量.这样就可以只观察一个线程的执行情况.

另一个常用的@err,hr
