File src/OFStdIOStream.m — part of check-in [f9cd4f9cab] at 2017-06-05 15:51:48 on branch trunk — OFStream: Don't throw when at end of stream
Instead, let reads return 0 and let writes append after the end. (user: js, size: 6626) [annotate] [blame] [check-ins using]

File src/OFStdIOStream.m — part of check-in [4f36894ce7] at 2017-06-05 17:36:28 on branch trunk — Clean up exceptions a little
This removes several initializers that omitted the errNo. Removing those
forces to think about whether there is a meaningful errNo to set instead
of just omitting it. (user: js, size: 6671) [annotate] [blame] [check-ins using]
