A file that was truncated on creation is indistinguishable from a file that was not truncated on creation: they're both just "files". So after open is done creating or truncating the file, it doesn't bother to "remember" that history. It only "remembers" important things, like whether the file is open for reading or writing.

Edited to add: These different kinds of flags have semi-official names. Notice that the "access mode" is not modifiable — you can't use fcntl to turn a read-only fd into a write-only fd.

This must be done as two separate system calls; there is no atomic or thread-safe way to accomplish it as far as I know. In fcntl. For example, on my MacBook the man page says:. In other words, there are exactly three bits you can set or unset on OS X. Whereas on Linux, the man page says this :. The "append-only"-ness of a file can be controlled at the filesystem level using the chattr utility. Here's a more systematic version of your test program.

It might not be of interest to you, but I learned something by writing it, so I'm leaving it here. Stack Overflow for Teams — Collaborate and share knowledge with a private group. BTW, I am wondering if the bash in insider preview has much more bugs fixed than the current stable bash? Several days ago I encountered another issue with scala and sbt not able to run on oracle java 1. To get an idea of how much has been changed take a look at the release notes. Thanks for the reply. I looked through the code but it wasn't immediately obvious what type of what type of file was being used.

Do you happen to know? If could you please take a strace of the scenario so we can check? I don't know.. Since I am currently not working on gem5 anymore, I will find some time later and run strace to collect what you need. Thanks for the follow-up.

WSL does not current support signal driven IO on tty devices, but we are tracking the work. Brian marked this fixedinsiderbuilds last fall.
