sd_bus_slot_set_description, sd_bus_slot_get_description - Set or query the description of bus slot objects
#include <systemd/sd-bus.h> int sd_bus_slot_set_description(sd_bus_slot* slot, const char *description); int sd_bus_slot_get_description(sd_bus_slot* bus, const char **description);
sd_bus_slot_set_description() sets the description string that is used in logging to the specified string. The string is copied internally and freed when the bus slot object is deallocated. The description argument may be NULL, in which case the description is unset. sd_bus_slot_get_description() returns a description string in description. If the string is not set, e.g. with sd_bus_slot_set_description(), and the slot is a bus match callback slot, the match string will be returned. Otherwise, -ENXIO is returned.
On success, these functions return 0 or a positive integer. On failure, they return a negative errno-style error code. Errors Returned errors may indicate the following problems: -EINVAL An required argument is NULL. -ENXIO The bus slot object has no description. -ENOMEM Memory allocation failed.
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
