Hello, I opened #FB19573116. Thank you for the help!

Thank you for the clarification. It seems that the solution based on IOKit may be too complex and unstable. So, I believe, the best approach is to use Core Audio (HAL). Thank you very much!

Thank you a lot for the help!

ok. thank you for the help! If I understand correctly, there is no any recommended API which provides users list.

This is DLP system which reports about users loggins. The daemon monitors the dynamic store which notify about console user changing. When console user is changed, I need to check whether the previous GUI session is closed or user is still logged in. Thank you for the help!

Thank you a lot for response! All I need is the list of logged-in users (GUI sessions), and getutxent() allows implementing trivial code. I haven't found any explicit restrictions on using getutxent() in daemons. Are there any direct daemon-safe way to get this information? (without agents) Can we say all user agents have already been launched by the time we receive the 'current console user changed' notification (SCDynamicStore)?

yes, I agree. It makes sense to implement this functionality in аgent. thank you!

Thank you for these tips. The improvements to ES_EVENT_TYPE_AUTH_IOKIT_OPEN are excellent news! Regarding CGEventTapCreate(), unfortunately, the CoreGraphics is not daemon-safe framework. Is there any way to implement keyboard locking directly at the daemon layer? Thank you a lot for your help!

Thank you a lot for this detailed explanation!

Thank you a lot for the help! I agree, looks like, there is no any sense to request storage usage so frequently if we are talking about collecting statistic only.

Thank you for answer! what are you trying to do? The customer wants real-time monitoring of SSD/HDD space usage alongside the partition scheme.

Thank you for such a detailed answer! Is there any sense in creating an enhancement request for a daemon-safe API (one that can be safely used within a daemon)? If I need to retrieve statistics once per second (as required by the customer), calling another process does not seem like the best solution.

thank you a lot!

thank you!

hello, As far as I know, Quartz Display Services is not daemon safe way. Moreover, CGDisplayUnitNumber() returns value which may vary across login sessions. CGDisplayIOServicePort() is deprecated. Are there any other way which is based on IOKit framework? Thank you for the help!
