This is the ReceiveSystemUpdate version of RequestSystemUpdateTaskRun.

This is the ReceiveSystemUpdate version of RequestSystemUpdateTaskRun.

This creates the [[#IAsyncResult]] object + the async [[#Contents_Delivery|thread]] which handles the [[#IAsyncResult]] operation, which uses the state previously setup by [[#Cmd69]]. This throws an error if the object was already created.

The port/Ipv4Address params originate from the [[NS_Services#RequestSendSystemUpdate|RequestSendSystemUpdate]] params.

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 arbitrary. This can be used for SystemUpdates via the above Send/Receive commands (which are then used via [[NS_Services#ns:su|ns:su]]). Application Patch content can also be transferred with this.

The Receive async [[#Cmd72|thread]] does the following:

The Receive async [[#RequestLocalCommunicationReceiveSystemUpdateTaskRun|thread]] does the following:

* Sets the <code>nn::fs::PriorityRaw</code> using a value loaded from state.

The Send async [[#Cmd77|thread]] does the following (the SendApplication [[#Cmd61|thread]] is identical except it uses different previously setup state):

The Send async [[#RequestLocalCommunicationSendSystemUpdateTaskRun|thread]] does the following (the SendApplication [[#RequestLocalCommunicationSendApplicationTaskRun|thread]] is identical except it uses different previously setup state):

* This is identical to the Receive thread except the called func is different.

* 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 [[#CreateLocalCommunicationSendSystemUpdateTask]]}

** 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).
