Question

I have a c++ program running two threads. thread A and thread B. is there a way to do step by step debugging of both threads in GDB? steps should be something like this:

1. Stop Threads A & B
2. Switch to thread A. continue one step.
3. Switch to thread B. continue two steps.

使用gdb命令“信息线程”查看该进程的所有线程，然后使用命令“ thread thread-id”顶部切换到所需的任何线程。
