NAME
sd_bus_list_names - Retrieve information about registered names on a busSYNOPSIS
#include <systemd/sd-bus.h>
int
sd_bus_list_names(sd_bus *bus,
char ***acquired,
char ***activatable);
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.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.
NOTES
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.SEE ALSO
