嵌入式 解决线程使用sleep或usleep等函数导致整个进程睡眠的问题

解决线程使用sleep或usleep等函数导致整个进程睡眠的问题：

获取当前时间的秒数

/*author : kjtime : 2013-12-06 21:36instruction:get the num of the current seconds*/int get_current_time_second(void){struct tm *tmnow;struct timeval tv;gettimeofday(&tv,NULL);tmnow = localtime(&tv.tv_sec);return tv.tv_sec;}

 

使用下面的函数接口完成替换线程中sleep计时

/*author : kjtime : 2013-12-06 21:42function :done the function of time interval in separate thread*/int pthread_count_second(int time_interval){int current_seconds = 0;int execl_seconds = 0;int set_time_interval = time_interval;    current_seconds = get_current_time_second();execl_seconds = current_seconds + set_time_interval;while(1){current_seconds = get_current_time_second();if((execl_seconds - current_seconds) == 0){break;}}return 0;}

 

call the time interval api example

/*author : kjtime : 2013-12-01instrucion:glitter :0 - direct set to board1 - speed slow2 - speed quickly*/int set_led_status(char *led_status,int glitter_type){    //int i_temp = 0;//the times need global variable    char set_led_status_buf[4] = {0};joseph_ipnc_param.joseph_ipnc_network_attr.joseph_ipnc_led_glitter_close = read_user_file("joseph_ipnc_led_glitter_close");    if(glitter_type == 0)    {    strcpy(set_led_status_buf,led_status);set_status_to_board(set_led_status_buf);    }    if(glitter_type == 1)    {    strcpy(set_led_status_buf,led_status);while(joseph_ipnc_param.joseph_ipnc_network_attr.joseph_ipnc_led_glitter_close == 1){    set_status_to_board(set_led_status_buf);    pthread_count_second(2);    set_status_to_board("00");//close the led    pthread_count_second(2);    joseph_ipnc_param.joseph_ipnc_network_attr.joseph_ipnc_led_glitter_close = read_user_file("joseph_ipnc_led_glitter_close");    //i_temp++;}//i_temp = 0;    }    if(glitter_type == 2)    {    strcpy(set_led_status_buf,led_status);while(joseph_ipnc_param.joseph_ipnc_network_attr.joseph_ipnc_led_glitter_close == 1){    set_status_to_board(set_led_status_buf);    pthread_count_second(1);    set_status_to_board("00");//close the led    pthread_count_second(1);    //i_temp++;    joseph_ipnc_param.joseph_ipnc_network_attr.joseph_ipnc_led_glitter_close = read_user_file("joseph_ipnc_led_glitter_close");}//i_temp = 0;    }    set_status_to_board(set_led_status_buf);alter_ipnc_param("joseph_ipnc_led_glitter_close","0");    return 0;}
