debugging - Solaris GDB : Howto pause execution?

Question

我正在使用 GDB 在 Solaris 10 x86 上调试封闭源程序。

我将 gdb 附加到程序并继续执行，但是当我想稍后暂停执行以检查一些内存时，我不能。当我按 CTRL-C 时，它只打印 ^C 而不是暂停程序并将我放到 (gdb) 提示符下。

bash-3.00# gdb --pid=1521

我如何回到 (gdb) 提示？我是不是做错了什么，或者我怎样才能让它发挥作用。

Answer 1

刚刚找到了一个解决方法。从另一个终端给出以下命令:

kill -INT 1521

GDB 将在被调试程序收到 SIGINT 后暂停执行。
