[0aaca60] | 22 | /* This stuff used to be in proxy.c too, but I split it off so BitlBee can |
---|
| 23 | use other libraries (like libevent) to handle events. proxy.c is one very |
---|
| 24 | nice piece of work from Gaim. It connects to a TCP server in the back- |
---|
| 25 | ground and calls a callback function once the connection is ready to use. |
---|
| 26 | This function (proxy_connect()) can be found in proxy.c. (It also |
---|
| 27 | transparently handles HTTP/SOCKS proxies, when necessary.) |
---|
| 28 | |
---|
| 29 | This file offers some extra event handling toys, which will be handled |
---|
| 30 | by GLib or libevent. The advantage of using libevent is that it can use |
---|
| 31 | more advanced I/O polling functions like epoll() in recent Linux |
---|
| 32 | kernels. This should improve BitlBee's scalability. */ |
