44 | <para>On failure, this call returns a negative errno-style error | |

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