Header: | Displays.h | Carbon status: | Supported | |
Reenables video mirroring disabled by the function DMUnblockMirroring. You should generally never need to use this function.
OSErr DMUnblockMirroring ();
A result code.
Because this function may move or purge memory blocks or access handles, you cannot call it at interrupt time.
Applications generally never need to use this function. In case you find a compelling need to change the users display configuration, this function is described here for completeness. Note that if your application uses Display Manager functions to change the display configuration of the users video devices, your application should make these changes only with the consent of the user. If your application must have a specific pixel depth, for example, it should display a dialog box that offers the user a choice between changing to that depth or canceling display of the image.
Supported in Carbon. Available in Carbon 1.0.2 and later when running Mac OS 8.1 or later.
