setBrightnesslevel
setBrightnesslevel is a software function or command used to adjust the brightness output of a display panel, lighting module, or similar device. It appears in device firmware, operating systems, mobile applications, and smart-home platforms to provide programmatic control over visual or ambient light levels. The exact effect depends on the target hardware and driver support.
Typical usage involves providing a brightness level parameter, often named level. Ranges vary: 0 to 100 as
The function may be synchronous or asynchronous. In asynchronous contexts it may return immediately and complete
Return value and error handling vary: a boolean success flag, a numeric result, or an error object.
Examples (conceptual): setBrightnesslevel(75); setBrightnesslevel(0.5, duration=200). In some environments brightness is controlled by the operating system or
