SD_BUS_SET_SENDER(3)          sd_bus_set_sender         SD_BUS_SET_SENDER(3)

NAME         top

       sd_bus_set_sender, sd_bus_get_sender - Configure default sender for
       outgoing messages

SYNOPSIS         top

       #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);

DESCRIPTION         top

       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.

RETURN VALUE         top

       On success, these functions return 0 or a positive integer. On
       failure, they return a negative errno-style error code.

       Returned errors may indicate the following problems:

           The bus connection has been created in a different process.

           The specified bus connection object is a not a direct but a
           brokered connection.

NOTES         top

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