| 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. | |
