推荐答案

通常，当有人说系统调用时，他们的意思是通过定义的入口点之一调用内核.虽然它在 iPhone 上在技术上是可行的，但你总是最好通过 libSystem 垫片，因为调用接口可能不稳定(例如它不在 Mac OS X 上).如果你这样做，我怀疑 Apple 会喜欢它，但我怀疑没有人真正考虑过它，他们也不太可能注意到.

Usually when someone says system call they mean calling into the kernel through one of the defined entry points. While its technically possible on iPhone, you are always better of going through the libSystem shims because the call interface is probably not stable (it isn't on Mac OS X for instance). I doubt Apple would like it if you did that, but I suspect no one as really thought about it much and they are unlikely to notice.

我不认为这就是你的意思.我认为您想使用 ISO/IEC 9899:1990 (C90) C 库函数系统".答案是否定的，你不能.

I don't think that is what you mean though. I think you want to use ISO/IEC 9899:1990 (C90) C libraray function "system". The answer to that is no, you can't.
