下面是我正在编写的一些代码的简化版本:
void
stuff(int fd)
{
int ret1, ret2;
char buffer[32];
ret1 = recv(fd, buffer, 32, MSG_PEEK | MSG_DONTWAIT);
/* Error handling -- and EAGAIN handling -- would go here. Bail if
necessary. Otherwise, keep going. */
/* Can this call to recv fail, sett
下面有密码。当我运行它时,会得到一个错误:

STDOUT:

我有一个检查管道是否存在的程序,它是在一个函数中编写的:
status = mkfifo("recv",0666);
fd1 = open("recv",O_WRONLY);
fd2 = open("sendd", O_RDONLY);
cout<<"we are checking botth bcz we have both read and write in the program------:)";
if(fd1 <0 && fd2 <0)
{
//strerror(errno
我有一个客户端和服务器机器。
从客户端,我发送一个linux命令,在80秒后回复。当服务器不回复initial80秒时,就会发生(s.recv)和超时错误。
请帮助我们在这里继续前进?
s= socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(300)
s.connect((hostname, self.port))

我正在用Python编写一个脚本,用于登录到ssh,并读取刚刚执行的命令的输出。我用paramiko包装来做这个。我正在尝试执行命令"top“,并将其输出打印到控制台上。不过,我不能这样做。请找到片段:
import sys
import time
import select
import paramiko
host = 'localhost'
i = 1
#
# Try to connect to the host.
# Retry a few times if it fails.
