event_callback() function

Callback registered in the netconn layer for each socket-netconn. Processes recvevent (data available) and wakes up tasks waiting for select.

Syntax

static void event_callback(struct netconn *conn,     enum netconn_evt evt,     u16_t len);
Implemented in sockets.c:2476

Arguments

conn

evt

len

Notes

for LWIP_TCPIP_CORE_LOCKING any caller of this function must have the core lock held when signaling the following events as they might cause select_list_cb to be checked: NETCONN_EVT_RCVPLUS NETCONN_EVT_SENDPLUS NETCONN_EVT_ERROR This requirement will be asserted in select_check_waiters()
