SD_BUS_R...HOD_ERROR(3) sd_bus_reply_method_error SD_BUS_R...HOD_ERROR(3)
sd_bus_reply_method_error, sd_bus_reply_method_errorf,
sd_bus_reply_method_errorfv, sd_bus_reply_method_errno,
sd_bus_reply_method_errnof, sd_bus_reply_method_errnofv - Reply
with an error to a D-Bus method call
#include <systemd/sd-bus.h>
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,
const char *format, ...);
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 e 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(3) may be returned.
Functions described here are available as a shared library, which
can be compiled against and linked to with the
libsystemd pkg-config(1) file.
All functions listed here are thread-agnostic and only a single
thread may operate on a given object at any given time. Different
threads may access the same object at different times. Multiple
independent objects may be used from different threads in
parallel.
The code described here uses getenv(3), which is declared to be
not multi-thread-safe. This means that the code calling the
functions described here must not call setenv(3) from a parallel
thread. It is recommended to only do calls to setenv() from an
early phase of the program when no other threads have been
started.
