netconn_delete() function

the netconn to delete

Send data over a TCP netconn.

Get and reset pending error on a netconn

Bind a netconn to a specific local IP address and port. Binding one netconn twice might not always be checked correctly!

Receive data (in form of a netbuf containing a packet buffer) from a netconn

Set a TCP netconn into listen mode

Accept a new connection on a TCP listening netconn.

Close a TCP netconn (doesn't delete it).

Send data over a UDP or RAW netconn (that is already connected).

Connect a netconn to a specific remote IP address and port.

Internal helper function to close a TCP netconn: since this sometimes doesn't work at the first attempt, this function is called from multiple places.

Get the local or remote IP address and port of a netconn. For RAW netconns, this returns the protocol instead of a port!

Receive data: actual implementation that doesn't care whether pbuf or netbuf is received (this is internal, it's just here for describing common errors)

Close or shutdown a TCP netconn (doesn't delete it).

Delete a netconn and all its resources. The pcb is NOT freed (since we might not be in the right thread context do this).

See if more data needs to be written from a previous call to netconn_write. Called initially from lwip_netconn_do_write. If the first call can't send all data (because of low memory or empty send-buffer), this function is called again from sent_tcp() or poll_tcp() to send more data. If all data is sent, the blocking application thread (waiting in netconn_write) is released.

Delete rcvmbox and acceptmbox of a netconn and free the left-over data in these mboxes

Setup a tcp_pcb with the correct callback function pointers and their arguments.

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

Send vectorized data atomically over a TCP netconn.

Close a netconn 'connection' and free all its resources but not the netconn itself. UDP and RAW connection are completely closed, TCP pcbs might still be in a waitstate after this returns.

Shut down one or both sides of a TCP netconn (doesn't delete it).

Disconnect a netconn from its current peer (only valid for UDP netconns).

Receive data (in form of a netbuf) from a UDP or RAW netconn

Receive data (in form of a pbuf) from a TCP netconn

Free a socket (under lock)

Free a socket's leftover members.

Allocate a new socket for a given netconn.

Send data (in form of a netbuf) to a specific remote IP address and port. Only to be used for UDP and RAW netconns (not TCP).

Bind a netconn to a specific interface and port. Binding one netconn twice might not always be checked correctly!

Receive data (in form of a netbuf) from a UDP or RAW netconn

Receive data (in form of a pbuf) from a TCP netconn
