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.
