如何获取gdb中当前已调试进程的pid? [英] How does one obtain the pid of the currently debugged process in gdb?

问题描述

在gdb内，什么命令将提供正在调试的进程的pid?

Inside gdb, what command will provide the pid of the process getting debugged?

大多数

Most of the google results discuss only how to attach gdb to a process once we know the pid.

推荐答案

一种简单的方法是info inferior.在这里，我正在用自身调试gdb，此命令显示了被调试对象的PID:

One simple way is info inferior. Here I'm debugging gdb with itself and this command shows the PID of the debuggee:

(top-gdb) info inferior
  Num  Description       Executable        
* 1    process 14068     /home/tromey/gdb/build/gdb/gdb 

您也可以只调用普通的C函数:

You can also just call the ordinary C function:

(top-gdb) print getpid()
$3 = 14068
