cont是continue的缩写,功能是运行到下一个断点处停止。 在GDB调试中,我们可以使用tbreak命令来设置1次性断点,就是说该断点使程序暂停之后,会自动消失。 如下图,首先我们输入delete命令来清空所有断点,也可以使用clear命令加对应行号,然后使用tbreak 9命令,在第9行设置临时断点 之后我们使用run命令,发现程序运行到第9...

breakpoint 可以根据行号、函数、条件生成断点,下面是相关命令以及对应的作用说明: watchpoint watchpoint是一种特殊类型的断点,类似于正常断点,是要求GDB暂停程序执行的命令。区别在于watchpoint没有驻留某一行源代码中,而是指示GDB每当某个表达式改变了值就暂停执行的命令。
