NAME

sd_bus_reply_method_return, sd_bus_reply_method_returnv - Reply to a D-Bus method call

SYNOPSIS

  #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);*

DESCRIPTION

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.

RETURN VALUE

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.

Message m is not a method reply message.

-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.

NOTES

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