+ * There is a single function in this category: SDL_GetPowerInfo().
+ *
+ * This function is useful for games on the go. This allows an app to know if
+ * it's running on a draining battery, which can be useful if the app wants to
+ * reduce processing, or perhaps framerate, to extend the duration of the
+ * battery's charge. Perhaps the app just wants to show a battery meter when
+ * fullscreen, or alert the user when the power is getting extremely low, so
+ * they can save their game.

+ * \param percent a pointer filled in with the percentage of battery life
+ *                left, between 0 and 100, or NULL to ignore. This will be
+ *                filled in with -1 we can't determine a value or there is no
