public bool close_checked (int fd) throws FileError
This wraps the close call.
In case of error, errno will be preserved, but the error will also be stored as a Error in throws. In case of success, errno is undefined.
Besides using Error, there is another major reason to prefer this function over the call provided by the system; on Unix, it will attempt to correctly handle eintr, which has platform-specific semantics.
It is a bug to call this function with an invalid file descriptor.
Since 2.76, this function is guaranteed to be async-signal-safe if (and only if) throws is
fd is a valid open file descriptor.

true on success, false if there was an error.
