SPI_GETSCREENREADER top-level constant Null safety
Determines whether a screen reviewer utility is running. A screen reviewer utility directs textual information to an output device, such as a speech synthesizer or Braille display. When this flag is set, an application should provide textual information in situations where it would otherwise present the information graphically.
The pvParam parameter is a pointer to a BOOL variable that receives TRUE if a screen reviewer utility is running, or FALSE otherwise.
Note: Narrator, the screen reader that is included with Windows, does not set the SPI_SETSCREENREADER or SPI_GETSCREENREADER flags.
