我需要为kgdb-gdb远程连接创建串口套接字。
就像
mkfifo
在你的系统上创建一个FIFO一样,我们如何创建套接字文件?
如果您尝试编写一个使用套接字的应用程序,@cidermonkey 接受的答案中的链接非常有用。如果你真的只是想创建一个,你可以用 python 来完成:
~]# python -c "import socket as s; sock = s.socket(s.AF_UNIX); sock.bind('/tmp/somesocket')"
~]# ll /tmp/somesocket
srwxr-xr-x. 1 root root 0 Mar 3 19:30 /tmp/somesocket
或者 使用一个小型 C 程序,例如,将以下内容保存到
create-a-socket.c
:
#include <fcntl.h>
#include <sys/un.h>
#include <sys/socket.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <unistd.h>
int main(int argc, char **argv)
{
// The following line expects the socket path to be first argument
char * mysocketpath = argv[1];
// Alternatively, you could comment that and set it statically:
//char * mysocketpath = "/tmp/mysock";
struct sockaddr_un namesock;
int fd;
namesock.sun_family = AF_UNIX;
strncpy(namesock.sun_path, (char *)mysocketpath, sizeof(namesock.sun_path));
fd = socket(AF_UNIX, SOCK_DGRAM, 0);
bind(fd, (struct sockaddr *) &namesock, sizeof(struct sockaddr_un));
close(fd);
return 0;
}
然后安装gcc,编译,哒哒:
~]# gcc -o create-a-socket create-a-socket.c
~]# ./create-a-socket mysock
~]# ll mysock
srwxr-xr-x. 1 root root 0 Mar 3 17:45 mysock
