On old sysvers the cmd impl for User/System are identical, except different params are used for the funcs called internally.


With [7.0.0+] [[#InitializeWithVersion|InitializeWithVersion]] is used instead. The cmd impl for Initialize uses [[#InitializeWithVersion|InitializeWithVersion]] with version=0.

The first func uses various [[Network_Interface_services|nifm]] funcs. The input value is used to determine the value for [[Network_Interface_services#CreateRequest|nn::nifm::RequestParameters]]: essentially, value 0x4 is used for ldn:u, and value 0x8 is used for ldn:s. The input value is also copied into state.

On old sysvers the cmd impl for User/System are identical, except different params are used for the funcs called internally: with User the u16 value is 0x5A, and the value for the second func is 1. With newer sysvers the cmd impl is now identical.


[[#GetState|State]] must be 0, this cmd eventually sets the State to value 1.

This is "nn::ldn::detail::IUserLocalCommunicationService".
This is "nn::ldn::detail::IUserLocalCommunicationService".
This is identical to [[#ISystemLocalCommunicationService]], except for the System-only cmd(s), and [[#Initialize_3|Initialize]]/[[#InitializeWithVersion_2|InitializeWithVersion]] differ.

=== Initialize ===
Takes an input PID and an u64 pid_placeholder.
This is used immediately after object creation.
With [7.0.0+] [[#InitializeWithVersion_2|InitializeWithVersion]] is used instead.
This is identical to [[#Initialize_2|Initialize]] except different params are used for the funcs called internally.
=== Finalize ===
No input/output.
This is used during service exit, prior to closing the object. Official sw will Abort if this fails.
=== InitializeWithVersion ===
Takes an input PID, a s32, and an u64 pid_placeholder.
Official sw uses the same input value as with [[#InitializeWithVersion|InitializeWithVersion]].
This is identical to [[#InitializeWithVersion|InitializeWithVersion]] except different params are used for the funcs called internally: the u16 value is 0x5A, and the value for the second func is 1.
