<hr><a name="_details"></a><h2>Detailed Description</h2>
The actual socketengine class presents the same interface on all operating systems, but its private members and internal behaviour should be treated as blackboxed, and vary from system to system and upon the config settings chosen by the server admin. 
<p>
The current version supports select, epoll and kqueue.

Constructor The constructor transparently initializes the socket engine which the ircd is using. 
<p>
Please note that if there is a catastrophic failure (for example, you try and enable epoll on a 2.4 linux kernel) then this function may bail back to the shell.

Add a file descriptor to the engine Use AddFd to add a file descriptor to the engine and have the socket engine monitor it. 
<p>
You must provide a type (see the consts in <a class="el" href="socketengine_8h.html">socketengine.h</a>) and a boolean flag to indicate wether to watch this fd for read or write events (there is currently no need for support of both).

Returns the type value for this file descriptor This function masks off the X_READBIT value so that the type of the socket can be obtained. 
<p>
The core uses this to decide where to dispatch the event to. Please note that some engines such as select() have an upper limit of 1024 descriptors which may be active at any one time, where others such as kqueue have no practical limits at all.
