Retrieves the pen's current status.


Uint32 SDL_GetPenStatus(SDL_PenID instance_id, float *x, float *y, float *axes, size_t num_axes);

Function Parameters

instance_id The pen to query.
x Out-mode parameter for pen x coordinate. May be NULL.
y Out-mode parameter for pen y coordinate. May be NULL.
axes Out-mode parameter for axis information. May be null. The axes are in the same order as ::SDL_PenAxis.
num_axes Maximum number of axes to write to "axes".

Return Value

Returns a bit mask with the current pen button states (::SDL_BUTTON_LMASK etc.), possibly ::SDL_PEN_DOWN_MASK, and exactly one of ::SDL_PEN_INK_MASK or ::SDL_PEN_ERASER_MASK , or 0 on error (see ::SDL_GetError()).


If the pen is detached (cf. ::SDL_PenConnected), this operation may return default values.


This function is available since SDL 3.0.0
