It will replace all characters which are invalid in a D-Bus object path by _ and a hexadecimal number. As a special case, the empty string will be replaced by a lone _. sd_bus_label_unescape() can be used to reverse this process. On success, a new NUL-terminated string will be returned. It must be free3d by the caller. If a memory allocation failure occurs, NULL will be returned. sd_bus_label_escape() and sd_bus_label_unescape() are available as a shared library, which can be compiled and linked to with the libsystemd-bus pkg-config1 file. systemd1, sd-bus3, free3
