WinDbg:dd <地址> L <长度> 的范围限制

Question

WinDbg 对 d 命令系列应用了范围限制。根据文档，限制为 256 MB。可以使用 L?语法。

L? Size (with a question mark) means the same as LSize, except that L? Size removes the debugger's automatic range limit. Typically, there is a range limit of 256 MB, because larger ranges are typographic errors. If you want to specify a range that is larger than 256 MB, you must use the L? Size syntax.

不过，我试着做了一个du 3ddabac0+8 L 0n6518040只有 6.5 MB，上面写着'du 3ddabac0+8 l 0n6518040 范围错误。

Answer 1

WinDbg 6.3 中的实际限制是 512kB。从 0x80001 或 0n524289 开始你需要使用 L？绕过限制。
