int sd_bus_reply_method_error(sd_bus_message *call,
const sd_bus_error *e);
int sd_bus_reply_method_errorf(sd_bus_message *call,
const char *name, const char *format,
...);
int sd_bus_reply_method_errorfv(sd_bus_message *call,
const char *name, const char *format,
va_list ap);
int sd_bus_reply_method_errno(sd_bus_message *call, int error,
const sd_bus_error *p);
int sd_bus_reply_method_errnof(sd_bus_message *call, int error,

int sd_bus_reply_method_errnofv(sd_bus_message *call, int error,
const char *format, va_list ap);
The sd_bus_reply_method_error() function sends an error reply to the
call message. The error structure e specifies the error to send, and
is used as described in sd_bus_message_new_method_error(3). If no
reply is expected to call, this function succeeds without sending a
reply.
The sd_bus_reply_method_errorf() is to sd_bus_reply_method_error()
what sd_bus_message_new_method_errorf() is to
sd_bus_message_new_method_error().
The sd_bus_reply_method_errno() is to sd_bus_reply_method_error()
what sd_bus_message_new_method_errno() is to
sd_bus_message_new_method_error().
The sd_bus_reply_method_errnof() is to sd_bus_reply_method_error()
what sd_bus_message_new_method_errnof() is to
sd_bus_message_new_method_error().
This function returns a non-negative integer if the error reply was
successfully sent or if call does not expect a reply. 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.
The error parameter error to sd_bus_reply_method_error is not
set, see sd_bus_error_is_set(3).
-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.
