一个浏览器

抄了一段别人的浏览器代码,自己编译成功了,不知道能不能,大家帮忙测试一下,
我的linux下不能上,麻烦大家了,

#include <unistd.h>
#include <sys/socket.h>
#include <stdio.h>
#include <sys/types.h>
#include <stdarg.h>
#include <netdb.h>
#include <stdlib.h>
int sock_connect(char *domain, int port)
{
int white_sock;
struct hostent *site;
struct sockaddr_in me;
site = gethostbyname(domain);
if (site==NULL)
return -2;
white_sock = socket(AF_INET, SOCK_STREAM, 0);
if (white_sock<0)
return -1;
memset (&me, 0, sizeof(struct sockaddr_in));
memcpy (&me.sin_addr, site->h_addr_list[0], site->h_length);
me.sin_family = AF_INET;
me.sin_port = htons(port);
return ( connect(white_sock, (struct sockaddr *)&me, sizeof(struct sockaddr)) <0) ? -1 : white_sock;
}
int sock_send( int sock, char *fmt,...)
{
char BUF[1024];
va_list argptr;
va_start(argptr, fmt);
vsprintf( BUF, fmt, argptr);
va_end(argptr);
return send(sock, BUF, strlen(BUF), 0);
}
int main( int argc, char *argv[])
{
int black_sock;
char bugs_bunny[3];
if (argc<2) return;
black_sock = sock_connect(argv[1], 80);
if (black_sock<0) return;
sock_send( black_sock, "GET / HTTP /1.0%c", 10);
sock_send( black_sock, "Host: %s%c", argv[1], 10);
sock_send( black_sock, "%c", 10);
while ( read(black_sock, bugs_bunny, 1) >0)
{
printf("%c",bugs_bunny[0]);
}
close(black_sock);
}

ok！没有问题。下面是我运行的结果：
