title: Memory buffers
|

|
Each connection has send and receive buffer,
|
||
|
|
[`struct mg_connection::send_mbuf`](#TODO)
|
||
|
|
and
|
||
|
|
[`struct mg_connection::recv_mbuf`](#ODO) respectively.
|
||
|
|
When data arrives,
|
||
|
|
Mongoose appends received data to the `recv_mbuf` and
|
||
|
|
triggers `MG_EV_RECV` event. User may send data back by calling one of the
|
||
|
|
output functions, like [`mg_send()`](#TODO) or
|
||
|
|
[`mg_printf()`](#TODO). Output functions append data to the
|
||
|
|
`send_mbuf`. When Mongoose
|
||
|
|
successfully writes data to the socket, it discards data from
|
||
|
|
[`mg_connection::send_mbuf`](#TODO) and
|
||
|
|
sends `MG_EV_SEND` event. When connection is closed, `MG_EV_CLOSE` event is sent.
