*
* There can be at most one EVS display object for the system and this function
* requests access to it. If the EVS display is not available or is already in use,
- * a null pointer is returned.
+ * the old instance shall be closed and give the new caller exclusive
+ * access.
* When done using the display, the caller may release it by calling closeDisplay().
* TODO(b/36122635) Reliance on the sp<> going out of scope is not recommended because the
* resources may not be released right away due to asynchronos behavior in the hardware binder.
