Function EOS_Lobby_GetRTCRoomName 

pub unsafe extern "C" fn EOS_Lobby_GetRTCRoomName(
    Handle: EOS_HLobby,
    Options: *const EOS_Lobby_GetRTCRoomNameOptions,
    OutBuffer: *mut c_char,
    InOutBufferLength: *mut u32,
) -> EOS_EResult

Get the name of the RTC room associated with a specific lobby a local user belongs to.

This value can be used whenever you need a RoomName value in the RTC_* suite of functions. RTC Room Names must not be used with EOS_RTC_JoinRoom, EOS_RTC_LeaveRoom, or EOS_RTC_AddNotifyDisconnected. Doing so will return EOS_AccessDenied or EOS_INVALID_NOTIFICATIONID if used with those functions.

This function will only succeed when called on a lobby the local user is currently a member of.

@param Options Structure containing information about the RTC room name to retrieve @param OutBuffer The buffer to store the null-terminated room name string within @param InOutBufferLength In: The maximum amount of writable chars in OutBuffer, Out: The minimum amount of chars needed in OutBuffer to store the RTC room name (including the null-terminator)

@return EOS_EResult containing the result of the operation. Possible result codes:

• EOS_Success if a room exists for the specified lobby, there was enough space in OutBuffer, and the name was written successfully
• EOS_NotFound if the lobby does not exist
• EOS_Disabled if the lobby exists, but did not have the RTC Room feature enabled when created
• EOS_InvalidParameters if you pass a null pointer on invalid length for any of the parameters
• EOS_LimitExceeded The OutBuffer is not large enough to receive the room name. InOutBufferLength contains the required minimum length to perform the operation successfully.
