gdb 附加到进程而不停止 [英] gdb attach to a process without stop

问题描述

每次我使用 gdb 附加到一个进程时，它都会停止目标程序，我需要输入 'cont' 让它离开.有没有办法在不停止进程的情况下附加到进程?如果进程停止一段时间后行为会有所不同，这会使事情变得更容易.

解决方案

你不能让它不停.但是，您可以立即继续...创建一个简单的批处理脚本，该脚本将附加到特定进程并在附加后立即继续执行:

gdb attach $1 -x <(echo "cont")

<块引用>

./附加PID

Everytime I attach to a process using gdb, it will stop the target program, and I need to type 'cont' to let it go. Is there a way to attach to a process without stopping it? This makes things easier if the process will behave differently if it stops for a while.

解决方案

You can't make it not stop. You can however instantly continue... Create a simple batch script which will attach to a specific process and instantly continuing execution after attaching:

gdb attach $1 -x <(echo "cont")

./attach PID
