| The error applet is used to display an error result by several titles and applets. (AppletId 0xE)
| | #REDIRECT [[Error_Applet]] |
| | |
| Depending on the type, the applet will display the error in several ways.
| |
| | |
| It takes two input storages: common arguments and a custom storage.
| |
| | |
| == Error applet types ==
| |
| | |
| === Common ===
| |
| | |
| For all of the following structures, the first two bytes are common and identify mode.
| |
| | |
| {| class="wikitable" border="1"
| |
| |-
| |
| ! Offset || Size || Typical Value || Notes
| |
| |-
| |
| | 0x0 || 1 || 0 || Error Applet Mode
| |
| |-
| |
| | 0x1 || 1 || 1 || Whether or not to use 'jump' mode
| |
| |}
| |
| | |
| In SDK, the jump mode byte is always one, except for nn::err::ShowErrorWithoutJump. HW-Testing has shown this to have no visual impact on error applet.
| |
| | |
| === Error (common one) ===
| |
| | |
| Takes a CommonArgs storage with version 0.
| |
| Uses a mode byte of 0 in the above struct.
| |
| | |
| ==== Custom storage ====
| |
| | |
| Unknown exact size, using size 20 seems to work fine.
| |
| | |
| The type (byte 0 of this storage) is 0.
| |
| | |
| {| class="wikitable" border="1"
| |
| |-
| |
| ! Offset || Size || Typical Value || Notes
| |
| |-
| |
| | 0x10 || 4 (u32) || 0 (2000-0000) || Result code, same Result type used everywhere in HOS.
| |
| |}
| |
| | |
| The error will display error code 2000-0000 if the Result is not set. The text is the default one.
| |
| | |
| === SystemError ===
| |
| | |
| Takes a CommonArgs storage with version 0.
| |
| Uses a mode byte of 1 in the above struct.
| |
| | |
| ==== Custom storage ====
| |
| | |
| SDK uses size 4120 for this storage.
| |
| | |
| The type (byte 0 of this storage) is 1.
| |
| | |
| {| class="wikitable" border="1"
| |
| |-
| |
| ! Offset || Size || Typical Value || Notes
| |
| |-
| |
| | 0x8 || 8 (u64) || 0 (0000-0000) || ErrorCode (not Result like in normal errors) of the error to use.
| |
| |-
| |
| | 0x18 || 0x800 || - || String of the text to be shown as a short description of the error.
| |
| |-
| |
| | 0x818 || 0x800 || - || String of the text to be shown as a more detailed description of the error.
| |
| |}
| |
| | |
| If the first text is not specified but the second one is, the applet will directly load the "Details" display with the second error text.
| |
| | |
| If both texts are set, the applet will load the dialog with "Close" and "Details" options, and will load the display mentiones above after selecting "Details".
| |
| | |
| If no ErrorCode is supplied, the applet will use 0000-0000.
| |
| | |
| === ApplicationError ===
| |
| | |
| Allows an application to show a custom-defined error text.
| |
| Uses a mode byte of 2 in the above struct.
| |
| | |
| The SDK uses size 4116 (0x1014) for this storage.
| |
| | |
| {| class="wikitable" border="1"
| |
| |-
| |
| ! Offset || Size || Typical Value || Notes
| |
| |-
| |
| | 0x8 || 4 (u32) || 0 (0000-0000) || ErrorCode of the error to use.
| |
| |-
| |
| | 0xC || 8 (u64) || 'en-US\0' || The Language of the following text. This uses the same language names as settings service.
| |
| |-
| |
| | 0x14 || 0x800 || - || String of the text to be shown as a short description of the error.
| |
| |-
| |
| | 0x814 || 0x800 || - || String of the text to be shown as a more detailed description of the error.
| |
| |}
| |
| | |
| On hardware, the short description will be displayed initially in a dialog box with the error code. There is a details button that when clicked will display the detailed description.
| |
| | |
| === ShowErrorRecord (ShowError with Timestamp) ===
| |
| | |
| Uses common arguments version 0 and a mode byte of 5.
| |
| | |
| Performs the same function as ShowError, but also displays the date and time of error.
| |
| | |
| {| class="wikitable" border="1"

| |
| ! Offset || Size || Typical Value || Notes
| |
| |-
| |
| | 0x8 || 8 (u64) || 0 (0000-0000) || Result code to use. This is formatted with the first u32 = description and second u32 = module + 2000.
| |
| |-
| |
| | 0x10 || 8 (u64) || 0 (Jan 1, 1970 00:00:00 AM) || POSIX time of the error to be displayed (as seconds since epoch).
| |
| |}
| |
| | |
| Unlike ShowError, this is fullscreen and not a dialog.
