But not so much overhead that anyone running code on a multi-tasking operating system would usually worry about.I am trying to do something as close to "real time" as possible. Using a system call (IMHO) just adds overhead.
It's because you want something which is different to what most others would do, are doing.Why is this so hard ?
You are trying to access something in the system domain from the user domain which is often challenging because that's generally discouraged, even prevented, to ensure security of the system.
You are basically swimming against the tide.
