24 | * There are two ways to register error maps with the error translation | |
25 | * logic: by using BUS_ERROR_MAP_ELF_REGISTER, which however only | |
26 | * works when linked into the same ELF module, or via | |
27 | * sd_bus_error_add_map() which is the official, external API, that | |
28 | * works from any module. | |
29 | * | |
30 | * Note that BUS_ERROR_MAP_ELF_REGISTER has to be used as decorator in | |
31 | * the bus error table, and BUS_ERROR_MAP_ELF_USE has to be used at | |
32 | * least once per compilation unit (i.e. per library), to ensure that | |
33 | * the error map is really added to the final binary. | |
