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.

Remarks

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