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 SwkbdIsCoveredWithSubWindow() SwkbdIsCoveredWithSubWindow__3RplFv Returns 0 or a status code from a subroutine.
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)
bool SwkbdIsSelectCursorActive() SwkbdIsSelectCursorActive__3RplFv Returns 1 or 0 (bool)
int SwkbdSetControllerRemo(nn::swkbd::ControllerType) SwkbdSetControllerRemo__3RplFQ3_2nn5swkbd14ControllerType Returns 0 or a status code from a subroutine.

int SwkbdSetInputFormString(wchar_t const *) SwkbdSetInputFormString__3RplFPCw Returns a value from a subroutine
int SwkbdSetReceiver(nn::swkbd::ReceiverArg const &) SwkbdSetReceiver__3RplFRCQ3_2nn5swkbd11ReceiverArg Returns a value from a subroutine
void SwkbdSetSelectFrom(int) SwkbdSetSelectFrom__3RplFi No return value. Returns argument 1 due to lazy programming.
void SwkbdSetUserControllerEventObj(nn::swkbd::IControllerEventObj*) SwkbdSetUserControllerEventObj__3RplFPQ3_2nn5swkbd19IControllerEventObj No return value. Returns argument 1 due to lazy programming.
void SwkbdSetUserSoundObj(nn::swkbd::ISoundObj*) SwkbdSetUserSoundObj__3RplFPQ3_2nn5swkbd9ISoundObj No return value. Returns argument 1 due to lazy programming.
void SwkbdSetVersion(int) SwkbdSetVersion__3RplFi No return value. Returns whatever OSReport returns due to lazy programming.
