This has several benefits, +including: + + - Simple interface + + - Back-end flexibility: It would be relatively easy to switch to any + other asynchronous I/O system. + + - Cleaner compilation: The ASIO headers include code which can + generate warnings in some compilers due to unused parameters and + such. Including ASIO header files throughout the Kea tree would + require us to relax the strictness of our error checking. Including + them in only one place allows us to relax strictness here, while + leaving it in place elsewhere. + +Some of the classes defined here--for example, IOSocket, IOEndpoint, +and IOAddress--are to be used by Kea modules as wrappers around +ASIO-specific classes. + + +Logging +------- + +At this point, nothing is logged by this low-level library. We may +revisit that in the future, if we find suitable messages to log, but +right now there are also no loggers initialized or called. |
