NAME         top

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

SYNOPSIS         top

       #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         top

       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         top

       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.

           Added in version 246.

       -EPERM
           Message call has been sealed.

           Added in version 246.

       -ENOTCONN
           The bus to which message call is attached is not connected.

           Added in version 246.

       -ENOMEM
           Memory allocation failed.

           Added in version 246.

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

NOTES         top

       Functions described here are available as a shared library, which
       can be compiled against and linked to with the
       libsystemd pkg-config(1) file.

       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.
