event_buffer_watermark_set — Set the watermarks for read and write events

说明

event_buffer_watermark_set ( resource $bevent , int $events , int $lowmark , int $highmark ) : void

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

参数

bevent: Valid buffered event resource.
events: Any combination of EV_READ and EV_WRITE.
lowmark: Low watermark.
highmark: High watermark.
