## 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

`-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.
