SD_BUS_REPLY_METHOD_ERROR(3)

  .SH "NAME" sd_bus_reply_method_error, sd_bus_reply_method_errorf, sd_bus_reply_method_errno, sd_bus_reply_method_errnof - Reply with an error to a method call
  .SH "SYNOPSIS"

#include <systemd/sd-bus.h>

      .HP u int sd_bus_reply_method_error(sd_bus_message *call, const sd_bus_error *e);
      .HP u int sd_bus_reply_method_errorf(sd_bus_message *call, const char *name, const char *format, ...);
      .HP u int sd_bus_reply_method_errno(sd_bus_message *call, int error, const sd_bus_error *p);

  .SH "DESCRIPTION"

    .PP 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_error(3). If no reply is expected to call, this function returns success without sending reply.
    .PP 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().
    .PP 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().
    .PP 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().

  .SH "RETURN VALUE"

    .PP These functions return 0 if the error reply was successfully sent or if none was expected, and a negative errno-style error code otherwise.

  .SH "ERRORS"

    .PP Returned errors may indicate the following problems:

      .PP -EINVAL

            The call message call is NULL.

            Message call is not a method call message.

            Message call is not attached to a bus.

            The error error parameter to sd_bus_reply_method_error is not set, see sd_bus_error_is_set(3).

          .RE
          .PP -EPERM

                Message call has been sealed.
              .RE
              .PP -ENOTCONN

                    The bus to which message call is attached is not connected.
                  .RE
                  .PP -ENOMEM

                        Memory allocation failed.
                      .RE

                    .PP In addition, any error message returned by sd_bus_send(1) may be returned.

                  .SH "NOTES"

                  .PP These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
