| Randy Eckenrode | Fish shell developer? | 17:47:01 |
| Ihar Hrachyshka | I was actually also looking at the same struct def. so looks like we may need to also define the __DARWIN_FD_SETSIZE otherwise we write past the end of the struct (I think) | 17:47:57 |
| Randy Eckenrode | Or malloc it based on the size of the incoming set. | 17:49:12 |
| Randy Eckenrode | Glib supports using cleanup functions to make that less messy. | 17:49:27 |
| Randy Eckenrode | Though if it’s a mask for all fds, you don’t really know the needed size. | 17:50:00 |

| Randy Eckenrode | Apple mentioned FreeBSD being unlimited. I agree we should probably increase the amount of memory it’s using (either by defining FD_SETSIZE or some other way). | 17:53:19 |
| Randy Eckenrode | Looks like (unsurprisingly) FreeBSD has a similar implementation.

| Randy Eckenrode | I guess FreeBSD doesn’t enforce the limit if you define it to something non-default. | 17:55:46 |
| Ihar Hrachyshka | so darwin just broke the api to pass posix | 17:56:22 |
| Ihar Hrachyshka | well, broke -> adjusted to standard | 17:56:33 |
