Solaris GDB：如何暂停执行？ [英] Solaris GDB: Howto pause execution?

问题描述

我正在使用GDB调试Solaris 10 x86上的封闭源代码程序。

我将gdb附加到程序并继续执行，但是当我想暂停执行时后来检查一些记忆我不能。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。

我是否回到（gdb）提示符？我做错了事情，我该怎么做才能使这个工作。

解决方案

刚刚找到了解决方法。从另一个终端给出以下命令：

  kill -INT 1521 
  

GDB将在调试程序接收到SIGINT时暂停执行。

I am using GDB to debug a closed source program on Solaris 10 x86.

I attach gdb to the program and continue execution, however when I want to pause execution later to examine some memory I cant. When I press CTRL-C it only prints ^C instead of pausing the program and dropping me to a (gdb) prompt.

How do I get back to a (gdb) prompt? Am I doing something wrong or how can I go about getting this to work.

解决方案

Just found a workaround. From another terminal give the following command:

kill -INT 1521

GDB will pause execution upon the debugged program receiving the SIGINT.
