This struct includes everything that is necessary to execute a function for a netconn in another thread context (mainly used to process netconns in the tcpip_thread context to be thread safe).
| struct { ... } api_msg::ad |
used for lwip_netconn_do_getaddr
| struct netbuf* api_msg::b |
used for lwip_netconn_do_send
| struct { ... } api_msg::bc |
used for lwip_netconn_do_bind and lwip_netconn_do_connect
| struct netconn* api_msg::conn |
The netconn which to process - always needed: it includes the semaphore which is used to block the application thread until the function finished.
| err_t api_msg::err |
The return value of the function executed in tcpip_thread.
| struct { ... } api_msg::jl |
used for lwip_netconn_do_join_leave_group
