idapython中ni-si的等价物是什么？

Question

我想制作一个简单的idapython脚本 它为某个特定的内存地址设置断点 然后继续使用一些规则过滤断点命中。。在

如果是gdb。我可以制作一个gdb脚本，比如

123678 0x458基点 c 如果~~~否则~~~ 镍 硅 ... c ... 在

我怎么能用idapython做这种事情呢？ 提前谢谢你

您正在查找dbg_step_into和{}。IDAAPI与调试器无关，它的GUI允许您设置所使用的调试器（您可能已经知道，它支持GDB）。有关API文档，请参见here。类似地，相关的IDA操作被记录为here（idaapi.request_step_into）。在

Here是取自IDApython存储库的一个用例，在这里部分复制，以防链接过时：
