11 | /* This comment is a kludge to get metaconfig to see the symbols |
| 12 | VAL_O_NONBLOCK |
| 13 | VAL_EAGAIN |
| 14 | RD_NODATA |
| 15 | EOF_NONBLOCK |
| 16 | and include the appropriate metaconfig unit |
| 17 | so that Configure will test how to turn on non-blocking I/O |
| 18 | for a file descriptor. See config.h for how to use these |
| 19 | in your extension. |
| 20 | |
| 21 | While I'm at it, I'll have metaconfig look for HAS_POLL too. |
