Sets the watermarks for read and write events. Libevent does not invoke
|
|
read callback unless there is at least <code class="parameter">lowmark</code> bytes
|
|
in the input buffer; if the read buffer is beyond the <code class="parameter">highmark</code>,
|
|
reading is stopped. On output, the write callback is invoked whenever the
|
|
buffered data falls below the <code class="parameter">lowmark</code>.
