Returns: u64

`SetLdnPid`

void SetLdnPid(u64 pid)

Set the PID that has opened ldn:u service.

Called immediately whenis created, BEFORE Initialize(). This allows BSD MITM to know which process to intercept even before the game calls Initialize().pidProcess ID that opened ldn:u, or 0 to clearparam

Called at startup to load the list of games that support LDN. This replaces any existing whitelist.game_idsVector of program IDs that support LDNparam

Parameters:

game_ids (const std::vector< u64 > &)

`IsLdnGame`

bool IsLdnGame(u64 program_id)

Check if a program_id is in the LDN whitelist.

`SetLdnState`

void SetLdnState(CommState state)

Set current LDN communication state.

Called by MITM service on state transitions.stateNew LDN stateparam

Parameters:

`GetLdnState`

CommState GetLdnState()

Get current LDN communication state.

Current LDN statereturn
