Can you use the CheckOpenResult function for this? Adding the errno to the error string generated there would be useful

Ack. Perhaps I should rename "CheckOpenResult" to something more generic like "CheckFileOpsResult"?

+1 -- if you can fix the small nit I will merge once the build runs. Thank you for the contribution!

Thanks, the Travis CI tubes are a bit clogged today so I may not be able to merge until later tonight or tomorrow morning |

@wesm Bah, I just noticed my patch has a bug; if truncate fails we will leak the file handle. I just resubmitted a fixed version. Thanks. |

I think this would be handled by RAII without this https://github.com/apache/arrow/blob/master/cpp/src/arrow/io/file.cc#L473. If there is an esoteric failure to close the file handle then this would bubble up the error, but I'm not sure why that would occur

Right, I missed that line in the dtor. Then I'll revert to the previous version of the patch.
