argument-passing 变元传递
To make one executable look like many executables, BusyBox exploits a seldom-used feature of argument passing to the main C function. Recall that the C main function is defined as follows
为了让一个可执行程序看起来就像是很多可执行程序一样,BusyBox 为传递给 C 的 main 函数的参数开发了一个很少使用的特性。
Like filter , map evaluates the string passed as its second argument, passing each list element in turn, via v: val.
和filter一样,map计算作为第二个参数传递的字符串,并且通过v: val传递每个列表元素。
That expression is a recursive call to lazy-seq-fibo, but this time, it is calling the two argument case, passing in 0 and 1 to it.
该表达式是对lazy - seq - fibo的一个递归调用,不过这次,它调用的是有两个参数的情况,并向其传递0和1。
And then I'll call fast max val passing at this extra argument of the memo.
然后我会调用快速maxval函数,而它是基于这个额外变量memo的。
