That has nothing to do with C. You would need to do the same thing in any language on any platform.

- bluetomcat 12y agoMost higher level languages do have wrappers around these calls, but you rarely have to worry about things such as async-signal-safety or EINTR, for example. Knowing why such things are problematic isn't of much interest to the average Python programmer, while essential for writing correct and safe C code.
- nknighthb 12y agoI wasn't talking about "higher level languages", really. Still, you have made a strange statement. Most obviously, if you don't worry about EINTR in Python, your code crashes. This was, in fact, the subject of a recent draft PEP (475) that generated a fair bit of discussion but not much consensus. To the extent you're better off in Python or any other high-level language than in C, it's because things are removed from your control. Obviously, if you can't do something in a language, you can't do it wrong. That is uninteresting. And of course EINTR and much signal behavior is POSIX-specific -- as in, you may not even have it (or necessarily anything like it) on other platforms. This, again, is not a "C" thing. All the world is not POSIX.
