Sorry for the late answer.

Why not stay compatible with other implementations?
That is _one_ dedicated result for errors and a separate variable "SDL_errno" for the error 
code.

To define it as (size_t)(-1) is fine even when size_t is unsigned. Then it is the maximum value. 
But having just one single value for errors makes checking simpler.
