Uint8 * SDL_GetKeyboardState

(

int *

numkeys

)

Get a snapshot of the current state of the selected keyboard.

Parameters:

numkeys

if non-NULL, receives the length of the returned array.

Returns:

An array of key states. Indexes into this array are obtained by using SDL_scancode values.

Example: Uint8 *state = SDL_GetKeyboardState(NULL); if ( state[SDL_SCANCODE_RETURN)] ) ... <RETURN> is pressed.

SDLKey SDL_GetKeyFromScancode

(

SDL_scancode

scancode

)

Get the key code corresponding to the given scancode according to the current keyboard layout.

See SDLKey for details.

SDL_GetKeyName()

const char * SDL_GetKeyName

(

SDLKey

key

)

Get a human-readable name for a key.

Returns:

A pointer to a UTF-8 string that stays valid at least until the next call to this function. If you need it around any longer, you must copy it. If the key doesn't have a name, this function returns "".

scancode

)

Get a human-readable name for a scancode.

Returns:

(

int

index

)

Set the index of the currently selected keyboard.
