| // A table of network states, to be included when building tabular things. |
| // |
| // This file is used to construct two things: an enumerated type in |
| // metrics_daemon.h, and a table of structures with state names in |
| // metrics_daemon.cc. Including this file ensures that the two tables are |
| // always in sync (and saves typing). I don't know of other ways of achieving |
| // the same result in C/C++, but it doesn't mean there isn't one. |
| |
| // Before you include this file, define STATE to do something useful, or else |
| // if will be a no-op. STATE will be undefined on exit. Don't worry about |
| // collisions for the STATE macro (as long as it's a macro) because the |
| // compiler will flag them---in that case, just change the name. If someone is |
| // misguided enough to use STATE for something other than a macro, the error |
| // messages will be slightly more complicated. |
