5 Some extra care is needed when using `liblttng-ust` with daemon
6 applications that call `fork()`, `clone()` or BSD's `rfork()` without
7 a following `exec()` family system call. The `liblttng-ust-fork`
8 library must be preloaded for the application.
13 <strong>LD_PRELOAD=liblttng-ust-fork.so</strong> ./app
16 Or, if you're using a tracepoint provider shared library:
19 <strong>LD_PRELOAD="liblttng-ust-fork.so /path/to/tp.so"</strong> ./app
