* You must check the return values of SDL function calls to determine when to
* appropriately call SDL_GetError(). You should *not* use the results of
* SDL_GetError() to decide if an error has occurred! Sometimes SDL will set
* an error string even when reporting success.
*
* SDL will *not* clear the error string for successful API calls. You *must*
* check return values for failure cases before you can assume the error
* string applies.
*
* Error strings are set per-thread, so an error set in a different thread
* will not interfere with the current thread's operation.
*
* The returned string is internally allocated and must not be freed by the
* application.
