Error Applet
This is the applet presented when a title displays an error message. See AM_services#Library_Applets.
All errors displayed by this applet get logged and can be viewed under 'Settings' > 'Support' > 'Error History'.
On pre-5.0.0 the specified LanguageCode has to be valid, otherwise a fatal-error is thrown. With [5.0.0+] it will use en-US when the LanguageCode is invalid.
ErrorContext
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x1F4 | String, should be NUL-terminated. |
| 0x1F4 | 0xC | ? |
ErrorCommonHeader
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x1 | u8 type |
| 0x1 | 0x1 | u8 jumpFlag. When clear, this indicates WithoutJump. |
| 0x2 | 0x3 | ? |
| 0x5 | 0x1 | u8 contextFlag. When set with type=0, indicates that an additional storage is pushed for #ResultBacktrace. [4.0.0+]: When set indicates that an additional storage is pushed for #ErrorContext. |
| 0x6 | 0x1 | u8 resultFlag. #ErrorCommonArg: When clear, ErrorCode is used, otherwise the applet generates the error-code from res. |
| 0x7 | 0x1 | u8 contextFlag2. Similar to contextFlag except for #ErrorCommonArg, indicating #ErrorContext is used. |
ErrorCommonArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader |
| 0x8 | 0x8 | #ErrorCode |
| 0x10 | 0x4 | Result res |
ErrorPctlArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader. type=4. |
| 0x8 | 0x4 | Result res |
This struct is 0xC-bytes. Used instead of #ErrorCommonArg where a Result error would have been displayed with type=0, for module=PCTL errors with desc 100-119. For this the applet will display the following dialog (without report logging): "This software is restricted by Parental Controls".
ErrorEulaData
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x20000 | data |
ErrorEulaArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader. jumpFlag = 1. |
| 0x8 | 0x4 | RegionCode |
This struct is 0xC-bytes.
- Eula: ErrorCommonHeader.type = 3. Displays the EULA.
- SystemUpdateEula: ErrorCommonHeader.type = 8. Displays the system-update EULA. Uses an additional IStorage containing #ErrorEulaData, from Applet_Manager_services#CreateTransferMemoryStorage with flag=false.
ErrorRecordArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader. type=5 and jumpFlag=1. |
| 0x8 | 0x8 | #ErrorCode |
| 0x10 | 0x8 | u64 POSIX timestamp |
The applet does not log an error report for this. Used by qlaunch for viewing previously logged errors via the "View the Error" button.
SystemErrorArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader. type=1. |
| 0x8 | 0x8 | #ErrorCode |
| 0x10 | 0x8 | LanguageCode |
| 0x18 | 0x800 | UTF-8 string dialogMessage |
| 0x818 | 0x800 | UTF-8 string fullscreenMessage, displayed when the user clicks on "Details". When not set this disables displaying Details. |
This struct is 0x1018-bytes.
ApplicationErrorArg
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x8 | ErrorCommonHeader. type=2 and jumpFlag=1. |
| 0x8 | 0x4 | u32 errorNumber. Raw decimal error number which is displayed in the dialog. |
| 0xC | 0x8 | LanguageCode |
| 0x14 | 0x800 | UTF-8 string dialogMessage |
| 0x814 | 0x800 | UTF-8 string fullscreenMessage, displayed when the user clicks on "Details". When not set this disables displaying Details. |
This struct is 0x1014-bytes.
ErrorCode
This is an u64 containing the error-code: the low u32 is the module portion which is normally set to module + 2000, and the high u32 is the error description.
ResultBacktrace
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x4 | s32 total entries |
| 0x4 | 0x4*total_entries | Array of Result |
Usage
User-processes should push a common arguments struct (version=0) as well as the Arg struct. Once the applet finishes running successfully, it may return an output storage in some cases. An u8 status value is located at +1, where non-zero indicates error.
