再比如下面的代码：

【 while (true)
{
/* produce an item in nextProduced */
while (counter == BUFFER_SIZE) ; /* do nothing */
buffer[in] = nextProduced;
in = (in + 1) % BUFFER_SIZE;
c ...

while (true)
{
/* produce an item in nextProduced */
while (counter == BUFFER_SIZE) ; /* do nothing */
buffer[in] = nextProduced;
in = (in + 1) % BUFFER_SIZE;
counter++;
}
