* Below are a few static members of the LSCPServer class. |
42 |
* The big assumption here is that LSCPServer is going to remain a singleton. |
43 |
* These members are used to support client connections. |
44 |
* Class handles multiple connections at the same time using select() and non-blocking recv() |
45 |
* Commands are processed by a single LSCPServer thread. |
46 |
* Notifications are delivered either by the thread that originated them |
47 |
* or (if the resultset is currently in progress) by the LSCPServer thread |
48 |
* after the resultset was sent out. |
49 |
* This makes sure that resultsets can not be interrupted by notifications. |
50 |
* This also makes sure that the thread sending notification is not blocked |
51 |
* by the LSCPServer thread. |
