Имя (Name)

sd_bus_list_names - Retrieve information about registered names on a bus

---

Синопсис (Synopsis)

#include <systemd/sd-bus.h>

int sd_bus_list_names(sd_bus *bus, char ***acquired, char ***activatable);

---

Описание (Description)

sd_bus_list_names() retrieves information about the registered names on a bus. If acquired is not NULL, this function calls org.freedesktop.DBus.ListNames[1] to retrieve the list of currently-owned names on the bus. If acquired is not NULL, the function calls org.freedesktop.DBus.ListActivableNames[2] to retrieve the list of all names on the bus that can be activated. Note that ownership of the arrays returned by sd_bus_list_names() in acquired and activatable is transferred to the caller and hence, the caller is responsible for freeing these arrays and their contents.

---

Возвращаемое значение (Return value)

On success, sd_bus_list_names() returns a non-negative integer. On failure, it returns a negative errno-style error code.

Errors Returned errors may indicate the following problems:

-EINVAL bus or both acquired and activatable were NULL.

-ENOPKG The bus cannot be resolved.

-ECHILD The bus was created in a different process.

-ENOMEM Memory allocation failed.

-ENOTCONN The bus is not connected.
