X That's just the special symbol in C that says don't pass X, that is don't pass a copy of X. Rather figure out where x is in memory, where he is in that frame and provide swap the numeric address in RAM of that value so that swap can go do anything it wants at that address.
這在C中是一個(gè)特殊的符號(hào)，指明不傳送，也不是傳遞X的拷貝，而是指出x在內(nèi)存中哪個(gè)地方,它在那個(gè)框架中的哪個(gè)地方,提供給swap它的地址值,這樣swap就可以使用那個(gè)地址中的數(shù)據(jù)。
