请教：向各位大哥请教一个 socket 编程中的进程问题，谢谢！

#include <stdio.h>
#include <string.h>
#include <time.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <unistd.h>

#define MAXLINE 1024
typedef struct sockaddr SA;

int main(int argc, char **argv)
{
int listenfd, connfd;
socklen_t len;
struct sockaddr_in servaddr, cliaddr;
char buff[MAXLINE];
time_t ticks;

listenfd = socket(AF_INET, SOCK_STREAM, 0);
bzero(&servaddr, sizeof(servaddr));
servaddr.sin_family = AF_INET;
servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
servaddr.sin_port = htons(1333); /* daytime server */

bind(listenfd, (SA *) &servaddr, sizeof(servaddr));

listen(listenfd, 5);

for ( ; ; ) {
len = sizeof(cliaddr);
connfd = accept(listenfd, (SA *) &cliaddr, &len);
printf("connection from %s, port %d\n",
inet_ntop(AF_INET, &cliaddr.sin_addr, buff, sizeof(buff)),
ntohs(cliaddr.sin_port));
ticks = time(NULL);
snprintf(buff, sizeof(buff), "%.24s\r\n", ctime(&ticks));
write(connfd, buff, strlen(buff));
close(connfd);
}
}

请教：
上面这段程序没有用到进程
各位大哥，如果我用进程的话

for ( ; ; ) {
len = sizeof(cliaddr);
connfd = accept(listenfd, (SA *) &cliaddr, &len);
printf("connection from %s, port %d\n",
inet_ntop(AF_INET, &cliaddr.sin_addr, buff, sizeof(buff)),
ntohs(cliaddr.sin_port));
ticks = time(NULL);
snprintf(buff, sizeof(buff), "%.24s\r\n", ctime(&ticks));
write(connfd, buff, strlen(buff));
close(connfd);
}

这里要怎么改啊？


谢谢！

解决描述符怎样在进程共享问题

duangw

在accept返回之后，调用fork创建子进程，由子进程来处理connfd；父进程则关闭connfd，继续循环。
