showuser.c

linux下开发的一款类似于QQ的网络聊天室

#include "main.h"
#define S_MAX 1024

int showuser(node *head,int socket)
{
	node *p;
	p=head;
	char buff[S_MAX]="\0";
	while(p!=NULL)
	{
		strcat(buff,p->user_name);
		strcat(buff,"  ");
		p=p->next;
	}
	if((send(socket,buff,strlen(buff),0))<0)
		return (-1);
	return 0;
}
