| 23 | VAL_O_NONBLOCK |
| 24 | VAL_EAGAIN |
| 25 | RD_NODATA |
| 26 | EOF_NONBLOCK |
| 27 | and include the appropriate metaconfig unit |
| 28 | so that Configure will test how to turn on non-blocking I/O |
| 29 | for a file descriptor. See config.h for how to use these |
| 30 | in your extension. |
| 31 | |
| 32 | While I'm at it, I'll have metaconfig look for HAS_POLL too. |
