Ctrl + c
Here is a task for tutorial_bcc_python_developer,how to deal with ctrl +c.From stackoverflow,the answer will be performaced:
from bcc import BPF
import signal
import sys
def bpf():
BPF(text='''
int kprobe__sys_sync(void *ctx)
{ bpf_trace_printk("Hello, yubo\\n");
return 0;}'''
).trace_print()
def signal_handler(signal, frame):
print('You pressed Ctrl+c!')
bpf()
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
print('press Ctrl+c')
signal.pause()
Here, maybe some issue exist.But i thought, the model will be the same as c
