I learned that syscall write to a regular file does not generate EINTR error(Why can't a write to disk be interrupted by signal?)
What about a read syscall in linux? Do "slow" devices include disk device?
(if SA_INTERRUPT is set)

2It is always better to write code that is able to handle an error return value with `errno == EINTR`, even if this error will not occur under certain preconditions. Can you guarantee that the file is a regular file? This might be a duplicate of https://stackoverflow.com/q/35224048/10622916 – Bodo Jan 10 '23 at 14:24
