27 | * The run-as process is launched by forking without an exec*() call. This means | |
28 | * that any resource allocated before the run-as worker is launched should be | |
29 | * cleaned-up after the fork(). This callback allows the user to perform this | |
30 | * clean-up. | |
31 | * | |
32 | * Note that the callback will _not_ be invoked if the LTTNG_DEBUG_NOCLONE | |
33 | * environment variable is set as the clean-up is not needed (and may not be | |
34 | * expected). | |
35 | * | |
36 | * A negative return value will cause the run-as process to exit with a non-zero | |
37 | * value. | |
