SD_BUS_REPLY_METHOD_RETURN(3)us_reply_method_returnUS_REPLY_METHOD_RETURN(3)
sd_bus_reply_method_return, sd_bus_reply_method_returnv - Reply to a
D-Bus method call
#include <systemd/sd-bus.h>
int sd_bus_reply_method_return(sd_bus_message *call,
const char *types, ...);
int sd_bus_reply_method_returnv(sd_bus_message *call,
const char *types, va_list ap);
sd_bus_reply_method_return() sends a reply to the call message. The
type string types and the arguments that follow it must adhere to the
format described in sd_bus_message_append(3). If no reply is expected
to call, this function succeeds without sending a reply.
On success, this function returns a non-negative integer. On failure,
it returns a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-EINVAL
The input parameter call is NULL.
Message call is not a method call message.
Message call is not attached to a bus.
-EPERM
Message call has been sealed.
-ENOTCONN
The bus to which message call is attached is not connected.
-ENOMEM
Memory allocation failed.
In addition, any error returned by sd_bus_send(1) may be returned.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
