Content can be transferred with a custom protocol over the network. This is intended for use with local [[LDN_services|ldn]] networks, however the used IP addresses can be arbitary. This can be used for SystemUpdates via the above Send/Receive commands (which are then used via [[NS_Services#ns:su|ns:su]]). Application content can also be transferred, which uses a similar (?) protocol.

See [[#Cmd69]]/[[#Cmd76]] for the socket setup during Receive/Send task creation. Receive system = client, while Send system = server.
 +
 
 +
The Receive async [[#Cmd72|thread]] does the following:
 +
* Sets the <code>nn::fs::PriorityRaw</code> using a value loaded from state.
 +
* Calls a func, and writes the returned Result into state.
 +
* Signals the async Event and returns.
 +
** That func does:
 +
** This handles installation, with messages being used via vtable funcptrs.
 +
 
 +
The Send async [[#Cmd77|thread]] does the following (the SendApplication [[#Cmd61|thread]] is identical except it uses different previously setup state):
 +
* This is identical to the Receive thread except the called func is different.
 +
** That func does:
 +
** Gets [[System_Settings|system-setting]] <code>nim.errorsimulate!error_localcommunication_result</code>, returning that as an error if set + non-zero.
 +
** Does socket setup:
 +
** Calls a func.
 +
** When any of the above fail (including the system-setting), the Result is written into state, then the Result is returned.
 +
** Lastly this returns 0.
 +
*** The above func does:
 +
*** This repeatedly receives requests, processes them, and sends the replies. This loop (and func) will only exit when an error occurs, or when request ID 0x0 is used (the latter causes the func to return 0).
 +
*** This handles the requests as required by the ID, no particular order is required by the server.
 +
*** All IDs in the below table are implemented by the server, for both SystemUpdate and Application.
 +
*** An error is thrown if the ID is unrecognized.
   −
Task [[#Cmd69|creation]] for Receive will eventually use the input addr/port with [[Sockets_services|connect()]], while the Send version will eventually do the same with [[Sockets_services|bind()]]. Hence, Receive system = client, while Send system = server.
+
The above socket setup for the Send async thread does the following:
 +
* Clears sockaddr_in and sets addrlen to 0x10.
 +
* Enters a loop which repeatedly calls a func. If that func fails, this will immediately return.
 +
* Within that loop the following is done:
 +
** sockfd = accept(listen_sockfd, &sockaddr_in, &addrlen); {handle error on fail - listen_sockfd is the saved sockfd from [[#Cmd76]]}
 +
** Exits the loop when the ipaddr within sockaddr_in matches the saved ipaddr in state from [[#Cmd76]] (originally from the cmd input param). Otherwise, close sockfd and continue the loop (with the above func being called again).
 +
* The following is done after the loop:
 +
* u64 tmpval=1; setsockopt(sockfd, SOL_SOCKET, SO_VENDOR + 0x1, &tmpval, sizeof(tmpval)); {handle error on fail}
 +
* Uses [[Network_Interface_services|nifm]] GetInternetConnectionStatus, returning an error if this is successful. Hence, the output from this is ignored.
 +
* Uses fcntl with F_GETFL/F_SETFL to clear O_NONBLOCK with sockfd, handling error on fail.
 +
* u32 tmpval2=0x4000;
 +
* u32 tmpval3=0x20000;
 +
* setsockopt(sockfd, SOL_SOCKET, SO_RCVBUF, &tmpval2, sizeof(tmpval2)); {error is ignored}
 +
* setsockopt(sockfd, SOL_SOCKET, SO_SNDBUF, &tmpval3, sizeof(tmpval3)); {error is ignored}
 +
* Writes sockfd to the output state sockfd and returns 0.
 +
** The func used with the above loop does the following:
 +
** Uses select() with input setup for {content of readfds = sockfd}, and timeval setup for a 1-second timeout. This is used repeatedly, until this returns an error (in which case error handling is done) or returns non-zero.
 +
** Then this returns 0.
