nsyskbd.rpl is the system library that allows applications to use USB keyboards plugged in the WiiU USB ports
Functions
Initialisation
| Prototype | Description |
|---|---|
char KBDSetup((void*)connection_callback,(void*)disconnection_callback,(void*)key_callback)
|
Initializes the USB keyboard library and return 0 if successfull. connection and disconnection callback are called repectively at the connection or disconnection of an usb keyboard; key callback is called when some key event occurs (2 times: press and release) |
char KBDTeardown()
|
Deinitializes the USB keyboard library and return 0 if the deinitialization was successfull |
char KBDInit((void*)unknown,(void*)connection_callback,(void*)disconnection_callback,(void*)key_callback);
|
Pass arguments to KBDSetup (probably an old function left for compatibility); should returns 0 if successfull |
char KBDExit();
|
Calls KBDTeardown() (probably an old function left for compatibility); should returns 0 if successfull |
Structures
| Prototype | Description |
|---|---|
typedef struct {
unsigned char ch;
unsigned char scancode;
unsigned int state; //1=press; 0=release; 3=keep pressing
char unknown[4]; //?
unsigned short UTF16;
} key_state; |
Used as argument of key_callback |
