SDL_GetError - Retrieve a message about the last error that occurred on the current thread.

       This function is available since SDL 3.2.0.

       It is possible for multiple errors to occur before calling

       SDL_GetError (). Only the last error is returned.

       The  message  is  only  applicable when an SDL function has signaled an error.  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  value  is  a  thread-local string which will remain valid until the current thread's error
       string is changed. The caller should make a copy if the value is needed after the next SDL API call.

       SDL_GetError - Retrieve a message about the last error that occurred on the current thread.

       Returns a message with information about the specific error that occurred, or an empty  string  if  there
       hasn't been an error message set since the last call to SDL_ClearError ().
