NAME

       sd_bus_message_set_destination, sd_bus_message_set_sender - Set the destination or sender
       service name of a bus message

SYNOPSIS

       #include <systemd/sd-bus.h>

       int sd_bus_message_set_destination(sd_bus_message *message, const char *destination);

       int sd_bus_message_set_sender(sd_bus_message *message, const char *sender);

DESCRIPTION

       sd_bus_message_set_destination() sets the destination service name for the specified bus
       message object. The specified name must be a valid unique or well-known service name.

       sd_bus_message_set_sender() sets the sender service name for the specified bus message
       object. The specified name must be a valid unique or well-known service name. This
       function is useful only for messages to send on direct connections as for connections to
       bus brokers the broker will fill in the destination field anyway, and the sender field set
       by original sender is ignored.

RETURN VALUE

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

ERRORS

       Returned errors may indicate the following problems:

       -EINVAL
           A specified parameter is invalid.

       -EPERM
           The message is already sealed.

       -EEXIST
           The message already has a destination or sender field set.

NOTES

       The sd_bus_message_set_destination() and sd_bus_message_set_sender() interfaces are
       available as a shared library, which can be compiled and linked to with the
       libsystemd pkg-config(1) file.
