How can I retrieve the gain and exposure values for each frame?

[LLits]

I am using the realsense SDK 2.0 with the RealSense D435. The programming language is use is C++. I am trying to get the gain and exposure each time new frames are retrieved. I can however not find the commands to get these gain and exposure values. What command should I use to get these values? Thank you in advance for helping and I hope to hear from you soon.

This link gives a script for getting the exposure values from metadata:

You can read the official metadata documentation here, which also describes a metadata attribute called GAIN_LEVEL

The link below gives advice about controlling the gain and exposure values.
