Swkbd.rpl

swkbd.rpl is the system library that allows applications to use the Wii U's on-screen keyboard. It is one of the only libraries to export C++ functions; thus it isn't known how to use them in homebrew at this point.

Functions

All the swkbd functions are C++ functions in the namespace Rpl::. To export them with OSDynLoad, you have to use their C symbol names (as listed).

Initialisation

Prototype	Symbol name (5.5.1)	Description	Reverse-Engineering Notes
void SwkbdCreate(unsigned char*, nn::swkbd::RegionType, unsigned int, FSClient*)	SwkbdCreate__3RplFPUcQ3_2nn5swkbd10RegionTypeUiP8FSClient	Sets up a structure in memory	No clear return value. Will return a mutex pointer (1004D294 on 5.5.1) from memory due to lazy programming.
void SwkbdDestroy()	SwkbdDestroy__3RplFv		No clear return value.

Keyboard Control

Prototype	Symbol name (5.5.1)	Description	Reverse-Engineering Notes
int SwkbdAppearInputForm(nn::swkbd::AppearArg const &)	SwkbdAppearInputForm__3RplFRCQ3_2nn5swkbd9AppearArg		Returns 0 or a status code from a subroutine.
int SwkbdAppearKeyboard(nn:swkbd::KeyboardArg)	SwkbdAppearKeyboard__3RplFRCQ3_2nn5swkbd11KeyboardArg		Returns 0 or a status code from a subroutine.
int SwkbdDisappearInputForm()	SwkbdDisappearInputForm__3RplFv		Returns 0 or a status code from a subroutine.
int SwkbdDissappearKeyboard()	SwkbdDisappearKeyboard__3RplFv		Returns 0 or a status code from a subroutine.
void SwkbdInactivateSelectCursor()	SwkbdInactivateSelectCursor__3RplFv	Disables selection?	No clear return value. Will return a pointer to some kind of internal struct due to lazy programming. Split up over several chunks.
int SwkbdInitLearnDic(void*)	SwkbdInitLearnDic__3RplFPv	Enables self-learning predictive text?	Returns 0 or a status code from a subroutine.
void SwkbdMuteAllSound(bool)	SwkbdMuteAllSound__3RplFb		Writes argument 1 to an internal struct, returns argument 1 due to lazy programming.

Logic

Prototype	Symbol name (5.5.1)	Description	Reverse-Engineering Notes
int SwkbdCalc(nn:swkbd::ControllerInfo const &)	SwkbdCalc__3RplFRCQ3_2nn5swkbd14ControllerInfo		Returns a value from an internal subroutine (presumably the response from the math operation).
int SwkbdCalcSubThreadFont(void)	SwkbdCalcSubThreadFont__3RplFv		Returns a value from an internal subroutine (presumably the response from the math operation).
int SwkbdCalcSubThreadPredict(void)	SwkbdCalcSubThreadPredict__3RplFv		Returns a value from an internal subroutine (presumably the response from the math operation).

Data

Prototype	Symbol name (5.5.1)	Description	Reverse-Engineering Notes
void SwkbdGetDrawStringInfo(nn::swkbd::DrawStringInfo*)	SwkbdGetDrawStringInfo__3RplFPQ3_2nn5swkbd14DrawStringInfo		No clear return value.
int SwkbdGetInputFormString()	SwkbdGetInputFormString__3RplFv		Returns 0 or a status code from a subroutine.
void SwkbdGetKeyboardCondition(nn::swkbd::KeyboardCondition *)	SwkbdGetKeyboardCondition__3RplFPQ3_2nn5swkbd17KeyboardCondition		No clear return value. Split into several chunks. Makes use of a function pointer from the stack.
int SwkbdGetStateInputForm()	SwkbdGetStateInputForm__3RplFv		Returns 0, 1, 2, or 3. Split into several chunks.
int SwkbdGetStateKeyboard()	SwkbdGetStateKeyboard__3RplFv		Returns 0, 1, 2, or 3.

int SwkbdIsDecideCancelButton(bool*)	SwkbdIsDecideCancelButton__3RplFPb		Returns 0 or a value from memory.
int SwkbdIsDecideOkButton(bool*)	SwkbdIsDecideOkButton__3RplFPb		Similar to IsDecideCancelButton. Returns 0 or a value from memory.
int SwkbdIsKeyboardTarget(nn::swkbd::IEventReceiver*)	SwkbdIsKeyboardTarget__3RplFPQ3_2nn5swkbd14IEventReceiver		Returns 0 or a value from memory.
int SwkbdIsNeedCalcSubThreadFont()	SwkbdIsNeedCalcSubThreadFont__3RplFv		Returns a value from a subroutine.
bool SwkbdIsNeedCalcSubThreadPredict()	SwkbdIsNeedCalcSubThreadPredict__3RplFv		Returns 1 or 0 (bool)
