网络程序

最近在学习Linux，在虚拟机上编了一个网络通信的程序但无法正常通信，各位大侠帮忙看一下：
功能就是客户端向服务器发送一个命令，服务把系统时间返回到客户端。
//客户端程序clienttime.c
#include <stdio.h>
#include <arpa/inet.h>
#include <sys/types.h>

printf("this is client time\n");

if (sockInit(&sockFd, &addrLocate, &addrRemote) < 0)
{
return -1;
}

if (sendto(sockFd, sendBuf, strlen(sendBuf), 0,

return 0;
}

程序运行的时候在红色的地方退出了，并且打印下来的errno = 22 ；对就的字符串为非法参数。
哪位大侠帮我找一下哪里错了。谢谢
