在Linux框上,我想检查特定的套接字文件是否存在。我知道套接字文件存在,但在bash中的检查没有向我显示这一点:
$ ls -l /var/run/supervisor.sock
srwxrw-rw- 1 root root 0 Jun 3 13:30 /var/run/supervisor.sock # <== THE FILE EXISTS!!
$ if [ ! -f /var/run/supervisor.sock ]; then echo 'file does not exist!'; fi
file does not exist!

我想使用netlink在应用程序和内核空间之间进行通信。我的Linux内核版本是2.6.28,下面是我的错误代码:

extern struct sock *netlink_kernel_cre
