sd_bus_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 object is deallocated. The
description
argument may be NULL
, in
which case the description is unset. This function must be called before the bus
has been started.
sd_bus_get_description()
returns a description string
in description
. This string may have been previously set
with sd_bus_set_description()
or
sd_bus_open_with_description(3)
or similar. If not set this way, a default string like "system
"
or "user
" will be returned for the system or user buses,
and NULL
otherwise.
sd_bus_set_anonymous()
enables or disables "anonymous
authentication", i.e. lack of authentication, of the bus peer. This function must
be called before the bus has been started. See the Authentication
Mechanisms section of the D-Bus specification for details.
sd_bus_set_trusted()
sets the "trusted" state on the
bus
object. If true, all connections on the bus are
trusted and access to all privileged and unprivileged methods is granted. This
function must be called before the bus has been started.
sd_bus_set_allow_interactive_authorization()
enables or disables interactive authorization for method calls. If true,
messages are marked with the
ALLOW_INTERACTIVE_AUTHORIZATION
flag specified by the
D-Bus
specification, informing the receiving side that the caller is prepared to
wait for interactive authorization, which might take a considerable time to
complete. If this flag is set, the user may be queried for passwords or
confirmation via polkit or a
similar framework.
sd_bus_get_allow_interactive_authorization()
returns
true if interactive authorization is allowed and false if not.
On success, these functions return 0 or a positive integer. On failure, they return a negative errno-style error code.
These APIs are implemented as a shared
library, which can be compiled and linked to with the
libsystemd
pkg-config(1)
file.
