NAME¶
sd_bus_list_names - Retrieve information about registered names on a bus
SYNOPSIS¶
#include <elogind/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
-ENOPKG
-ECHILD
-ENOMEM
-ENOTCONN
NOTES¶
These APIs are implemented as a shared library, which can be compiled and linked to with the libelogind pkg-config(1) file.
