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