SD_BUS_SET_SENDER(3) sd_bus_set_sender SD_BUS_SET_SENDER(3)
sd_bus_set_sender, sd_bus_get_sender - Configure default sender for
outgoing messages
#include <systemd/sd-bus.h>
int sd_bus_set_sender(sd_bus *bus, const char* name);
int sd_bus_get_sender(sd_bus *bus, const char** name);
sd_bus_set_sender() configures the default sender service name to use
for outgoing messages. The service name specified in the name
parameter is set on all outgoing messages that are sent on the
connection and have no sender set yet, for example through
sd_bus_message_set_sender(3). Note that this function is only
supported on direct connections, i.e. not on connections to a bus
broker as the broker will fill in the sender service name
automatically anyway. By default no sender name is configured, and
hence messages are sent without sender field set. If the name
parameter is specified as NULL the default sender service name is
cleared, returning to the default state if a default sender service
name was set before. If passed as non-NULL the specified name must be
a valid unique or well-known service name.
sd_bus_get_sender() may be used to query the current default service
name for outgoing messages.
On success, these functions return 0 or a positive integer. On
failure, they return a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-ECHILD
The bus connection has been created in a different process.
-EPERM
The specified bus connection object is a not a direct but a
brokered connection.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
