 `uiInit()` initializes libui. It returns `true` on success and `false` on failure; in the event of a failure, `err` is filled with relevant information explaining the failure.
 
-`err` is required and must be properly initialized. If `err` is `NULL` or `err->Size` does not match `sizeof (uiError)`, `uiInit()` immediately returns zero without doing anything. If any of the other fields of `err` are not zero-initialized as with `memset(0)`, the behavior is undefined.

 `options` must be `NULL`; no options are currently defined. If `options` is not `NULL`, `uiInit()` will return an error without initializing anything.
