虽然info命令非常强大,但GDB中还有许多其他命令也可以提供类似的功能。例如,list命令可以显示源代码,而show命令可以显示GDB的配置信息。但是,info命令的优势在于它提供了一个统一的接口来查询各种信息,这使得它在日常调试中非常实用。 正如庄子在《逍遥游》中所说:“大知闲闲,小知间间。”在编程的世界里,我们需要既...

Examine Memory using x Many developers know how to use GDB’s print, but less know about the more powerful x (for “examine”) command. The x command is used to examine memory using several formats. My most common use of x is looking at the stack memory of a system that doesn’t ...
