NAME

6       sd_bus_reply_method_error, sd_bus_reply_method_errorf,

SYNOPSIS

11       #include <systemd/sd-bus.h>
12
13       int sd_bus_reply_method_error(sd_bus_message *call,
14                                     const sd_bus_error *e);
15
16       int sd_bus_reply_method_errorf(sd_bus_message *call, const char *name,
17                                      const char *format, ...);
18
19       int sd_bus_reply_method_errno(sd_bus_message *call, int error,
20                                     const sd_bus_error *p);
21
22       int sd_bus_reply_method_errnof(sd_bus_message *call, int error,
23                                      const char *format, ...);

DESCRIPTION

26       The sd_bus_reply_method_error() function sends an error reply to the
27       call message. The error structure e specifies the error to send, and is
28       used as described in sd_bus_message_new_error(3). If no reply is
29       expected to call, this function returns success without sending reply.
30
31       The sd_bus_reply_method_errorf() is to sd_bus_reply_method_error() what
32       sd_bus_message_new_method_errorf() is to
33       sd_bus_message_new_method_error().
34
35       The sd_bus_reply_method_errno() is to sd_bus_reply_method_error() what
36       sd_bus_message_new_method_errno() is to
37       sd_bus_message_new_method_error().
38
39       The sd_bus_reply_method_errnof() is to sd_bus_reply_method_error() what
40       sd_bus_message_new_method_errnof() is to
41       sd_bus_message_new_method_error().
42

RETURN VALUE

44       These functions return 0 if the error reply was successfully sent or if
45       none was expected, and a negative errno-style error code otherwise.
46
47   Errors
48       Returned errors may indicate the following problems:
49
50       -EINVAL
51           The call message call is NULL.
52
53           Message call is not a method call message.
54
55           Message call is not attached to a bus.
56
57           The error error parameter to sd_bus_reply_method_error is not set,
58           see sd_bus_error_is_set(3).
59
60       -EPERM
61           Message call has been sealed.
62
63       -ENOTCONN
64           The bus to which message call is attached is not connected.
65
66       -ENOMEM
67           Memory allocation failed.
68
69       In addition, any error message returned by sd_bus_send(1) may be
70       returned.
