Function Documentation

◆ lwip_netconn_do_accepted()

void lwip_netconn_do_accepted ( void *  m)

Indicate that a TCP pcb has been accepted Called from netconn_accept

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_bind()

void lwip_netconn_do_bind ( void *  m)

Bind a pcb contained in a netconn Called from netconn_bind.

Parameters
mthe api_msg_msg pointing to the connection and containing the IP address and port to bind to

◆ lwip_netconn_do_close()

void lwip_netconn_do_close ( void *  m)

Close or half-shutdown a TCP pcb contained in a netconn Called from netconn_close In contrast to closing sockets, the netconn is not deallocated.

Parameters

void lwip_netconn_do_delconn ( void *  m)

Delete the pcb inside a netconn. Called from netconn_delete.

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_disconnect()

void lwip_netconn_do_disconnect ( void *  m)

Parameters
mthe api_msg_msg pointing to the connection to disconnect

◆ lwip_netconn_do_getaddr()

void lwip_netconn_do_getaddr ( void *  m)

Return a connection's local or remote address Called from netconn_getaddr

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_gethostbyname()

void lwip_netconn_do_gethostbyname ( void *  arg)

Execute a DNS query Called from netconn_gethostbyname

Parameters
argthe dns_api_msg pointing to the query

◆ lwip_netconn_do_join_leave_group()

void lwip_netconn_do_join_leave_group ( void *  m)

Join multicast groups for UDP netconns. Called from netconn_join_leave_group

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_listen()

void lwip_netconn_do_listen ( void *  m)

Set a TCP pcb contained in a netconn into listen mode Called from netconn_listen.

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_newconn()

void lwip_netconn_do_newconn ( void *  m)

Create a new pcb of a specific type inside a netconn. Called from netconn_new_with_proto_and_callback.

Parameters
mthe api_msg_msg describing the connection type

◆ lwip_netconn_do_recv()

void lwip_netconn_do_recv ( void *  m)

Indicate data has been received from a TCP pcb contained in a netconn Called from netconn_recv

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_send()

void lwip_netconn_do_send ( void *  m)

Send some data on a RAW or UDP pcb contained in a netconn Called from netconn_send

Parameters
mthe api_msg_msg pointing to the connection

◆ lwip_netconn_do_write()

void lwip_netconn_do_write ( void *  m)

Send some data on a TCP pcb contained in a netconn Called from netconn_write

Parameters
mthe api_msg_msg pointing to the connection

◆ netconn_alloc()

struct netconn* netconn_alloc ( enum netconn_type  t,
netconn_callback  callback 
)

Create a new netconn (of a specific type) that has a callback function. The corresponding pcb is NOT created!

Parameters
tthe type of 'connection' to create (
See also
enum netconn_type)
Parameters
callbacka function to call on status changes (RX available, TX'ed)
Returns
a newly allocated struct netconn or NULL on memory error

◆ netconn_free()

void netconn_free ( struct netconn conn)

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

Parameters
connthe netconn to free
