| 00:01 | <&McMartin> | That's the receive end. What's the send end? |
| 00:03 | <&[R]> | The pselect() function shall examine the file descriptor sets whose addresses are passed in the readfds, writefds, and errorfds parameters to see whether some of their descriptors are ready for reading, are ready for writing, or have an exceptional condition pending, respectively. The select() function shall be equivalent to the pselect() function, except as follows: [nothing about ready for writting] |
| 00:06 | <&McMartin> | Right, what I mean is, that's how I know that a nonblocking operation I fired off in the past is now done |
| 00:07 | <&McMartin> | My next question is "how do I fire off a nonblocking operation"? The man pages for open(2) have several options that look like they might be that but seem not to be; O_ASYNC is only for sockets or socket-like things, and O_NODELAY apparently still blocks. |
| 00:11 | <&McMartin> | It looks like there's some kind of specialized set of aio_* functions, too |

| 00:22 | <&ToxicFrog> | Yeah, I think aio(7) is what you wat |
| 00:24 | <&McMartin> | Really it's more "We've tried to do async I/O a thousand different ways, and all of them have remnants in various parts of the ecosystem" |
| 00:24 | <&McMartin> | And this is one of the odd cases where Windows is clearer about which technologies exist than Unix is~ |
