Raymond Chen
Raymond Chen

Via a customer liaison, we received what seemed like a simple question: "How can I detect whether a Windows machine is big-endian or little-endian?" You could actually answer this question (say by coughing up a code fragment that stores a 16-bit value to memory and then takes it apart into bytes to see how it got stored, or by simply hard-coding ...

Raymond Chen
Raymond Chen

The and functions require that the handle you provide by synchronous. (In other words, that they not be opened with .) A customer submitted the following question: We have been using asynchronous file handles with the . Every so often, the call to will fail, but we discovered that as a workaround, we can just retry the operation, and it will ...
