Reset the sent- and recv-callbacks.

Parameters:
pcbthe tcp pcb to reset callbacks
hsconnection state to free

Definition at line 582 of file lwip_httpd.c.

static void http_eof ( struct tcp_pcb *  pcb,
struct http_state *  hs 
) [static]

End of file: either close the connection (Connection: close) or close the file (Connection: keep-alive)
