-`LTTNG_UST_LOADED`::
-    Set internally by `liblttng-ust`'s constructor. Can be used by
-    applications to detect if lttng-ust is loaded, even if liblttng-ust
-    is not directly linked by the application. This environment
-    variable stays set across fork and exec, so an application could
-    observe this environment variable being set if a parent process had
-    lttng-ust loaded when issuing fork, even if this application does
-    not have lttng-ust in its address space.

 `LTTNG_UST_REGISTER_TIMEOUT`::
     Waiting time for the _registration done_ session daemon command
     before proceeding to execute the main program (milliseconds).
