自定义函数printf_line

//输出line_coords的坐标信息void printf_line(UF_CURVE_line_t line_coords){    UF_UI_open_listing_window();        char str[128]="start_point\t";    UF_UI_write_listing_window(str);    for (int i=0;i<=2;i++)    {        char str[128]="";        sprintf(str,"%lf\t",line_coords.start_point[i]);        UF_UI_write_listing_window(str);    }    sprintf(str,"\n");    UF_UI_write_listing_window(str);    sprintf(str,"end_point\t");    UF_UI_write_listing_window(str);    for (int i=0;i<=2;i++)    {        char str[128]="";        sprintf(str,"%lf\t",line_coords.end_point[i]);        UF_UI_write_listing_window(str);    }}

 

函数入口：

/* TODO: Add your application code here */    double start[3]={
    0.0,0.0,0.0};    double end[3]={
    100.0,100.0,100.0};    tag_t line_tag=NULL_TAG;    UF_CURVE_line_t line_coords;    create_line_twopiont(start,end,&line_tag);    tag_t curve_id=NULL_TAG;    curve_id=line_tag;    UF_CURVE_ask_line_data(curve_id,&line_coords);//查询结构体line_coords起点、终点函数    printf_line(line_coords);    /* Terminate the API environment */
