不是一个评论，而是一个goto标签

我能说什么呢?我当时是实习生，夏天快结束了。我们可以说，我对我的文件责任缺乏认真的承诺。

i++; // increment variable i

在linux 1.0内核调度器(schedule .c)中:

Dijkstra可能讨厌我。

/*
 *  'schedule()' is the scheduler function. It's a very simple and nice
 * scheduler: it's not perfect, but certainly works for most things.
 * The one thing you might take a look at is the signal-handler code here.
 *
 *   NOTE!!  Task 0 is the 'idle' task, which gets called when no other
 * tasks can run. It can not be killed, and it cannot sleep. The 'state'
 * information in task[0] is never used.
 *
 * The "confuse_gcc" goto is used only to get better assembly code..
 * Dijkstra probably hates me.

一个文件中5000多行代码中很少的一些注释 事实上，我和那个为自己的编码风格辩护的程序员有过一次争论…… 无可奉告! 没有评论;-)(或者很少) 遗憾的是，这是产品代码。

offset=1;
for (i=0;i<=len;i++)
    {
    if ((i!=0)&&(i<len)) //-3
        {
        switch(mess[i])
            {
            case ETX:
            case ETB:
            case DLE:
                buf[offset]=DLE;
                offset++;
                break;
            }
        }
    buf[offset]=mess[i];
    offset++;
    }

我喜欢这个开关!

for (n=0;n<offset;n++)
{
    Sleep(TR);  //Modif A
    Sleep(T);//
    FWriteFile(hCom,buf+n,1,&dwMot,NULL);
    if (ECHO)
        FReadFile(hCom,tab,1,&dwMot,NULL);
}

不，没有注释解释什么“修改A”是在标题。

if (GetFileSize(hSlotFile,NULL)==3600)   //5*720

720是多少?
