Detailed Description

Shared implementation of a bufferevent.

This type is exposed only because it was exposed in previous versions, and some people's code may rely on manipulating it. Otherwise, you should really not rely on the layout, size, or contents of this structure: it is fairly volatile, and WILL change in future versions of the code.

Field Documentation

struct bufferevent_ops* bufferevent::be_ops

Pointer to a table of function pointers to set up how this bufferevent behaves.

short bufferevent::enabled

Events that are currently enabled: currently EV_READ and EV_WRITE are supported.

struct event_base* bufferevent::ev_base

Event base for which this bufferevent was created.

struct event bufferevent::ev_read

A read event that triggers when a timeout has happened or a socket is ready to read data.

Only used by some subtypes of bufferevent.

struct event bufferevent::ev_write

A write event that triggers when a timeout has happened or a socket is ready to write data.

Only used by some subtypes of bufferevent.

struct evbuffer* bufferevent::input

An input buffer.

Only the bufferevent is allowed to add data to this buffer, though the user is allowed to drain it.

struct evbuffer* bufferevent::output

An input buffer.

Only the bufferevent is allowed to drain data from this buffer, though the user is allowed to add it.
