模拟鼠标事件的处理

作者:  时间: 2011-01-04
板子上的USB接口坏掉了,为了重现有鼠标时的状态,现做一个模拟鼠标:
input.h
usbmouse.h
 
struct mouse_my g_mt;
int mouse_state;
#define BUFFER 800
#define SERV_PORT 7838
void *read_uart_mouse(void *para)
{
        int sockfd;
        //socklen_t len;
        socklen_t src_len;
        struct sockaddr_in servaddr, cliaddr;
        char msg[BUFFER];
        sockfd = socket(AF_INET, SOCK_DGRAM, 0); /* create a socket */
        /* init servaddr */
        bzero(&servaddr, sizeof(servaddr));
        servaddr.sin_family = AF_INET;
        servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
        servaddr.sin_port = htons(SERV_PORT);
        /* bind address and port to socket */
        if(bind(sockfd, (struct sockaddr *)&servaddr, sizeof(servaddr)) == -1)
        {
          perror("bind error");
        }
        src_len = sizeof(cliaddr);
        while(1)
        {
                 if(recvfrom(sockfd, msg, BUFFER, 0, (struct sockaddr *)&cliaddr, &src_len)< 0)
                {
                          perror("receive error!\n");
                }else{
                mouse_state = 1;
                memcpy(&g_mt,msg,sizeof(struct mouse_my));
                memset(msg,0,sizeof(msg));
                }
        }
}
