NAME         top

       sd_bus_list_names - Retrieve information about registered names
       on a bus

SYNOPSIS         top

       #include <systemd/sd-bus.h>

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

DESCRIPTION         top

       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         top

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

       Returned errors may indicate the following problems:

           bus or both acquired and activatable were NULL.

           The bus cannot be resolved.

           The bus was created in a different process.

           Memory allocation failed.

           The bus is not connected.

NOTES         top

       These APIs are implemented as a shared library, which can be
       compiled and linked to with the libsystemd pkg-config(1) file.
