sockclient.c

这是一个用c语言和MiniGUI工具编写的数据采集服务器程序

#include "sockclient.h"


extern serv_addr[16];
extern struct sockaddr_in addr;
extern int sockfd;
extern int serv_port;


void initsocket(void)
{

	struct hostent *host;

	if((host=gethostbyname(serv_addr))==NULL)
	{
		MessageBox(NULL, "gethostbyname error", "aa", MB_OK);
		return;
	}

	if((sockfd=socket(AF_INET, SOCK_STREAM, 0))==-1)
	{
		
		MessageBox(NULL, "socket error", "aa", MB_OK);
		return;
	}

//	fcntl(sockfd, F_SETFL, O_NONBLOCK);

	addr.sin_family=AF_INET;
	addr.sin_port=htons(serv_port);
	addr.sin_addr=*((struct in_addr*)host->h_addr);
	bzero(&(addr.sin_zero), 8);

	if(connect(sockfd, (struct sockaddr*)&addr, sizeof(struct sockaddr))==-1)
	{
		
		MessageBox(NULL, "connect error", "aa", MB_OK);
		close(sockfd);
//		return;
	}
