| 47 | <para>On failure, this call returns a negative errno-style error | |
| 48 | code. If the system was booted up with systemd as init system, | |
| 49 | this call returns a positive return value, zero otherwise.</para> | |

| 57 | <para>Internally, this function checks whether the directory | |
| 58 | <filename>/run/systemd/system/</filename> exists. A simple check | |
| 59 | like this can also be implemented trivially in shell or any other | |
| 60 | language.</para> | |
