The Sender C API can be used to send asynchronous messages to native code running in other threads.

• Lua objects implementing the Sender C API can send asynchronous messages.
• Native C code invoking the Sender C API can read the asynchronous messages from any thread.

Lua objects implementing the Sender C API must have an associated meta table entry _capi_sender delivered by the C API function sender_get_capi() and the associated C API function toSender() must return a valid pointer for the given sender object. For further documentation see sender_capi.h.

• mtmsg buffer objects are implementing the Sender C API. If messages are added to the buffer, native C code can read the message from this buffer by invoking the Sender C API.

• auproc MIDI sender processor objects are sending midi messages that are given by a registered sender object to an auproc-capi connector, see auproc.new_midi_sender() and ljack/example04.lua.

• auproc AUDIO sender processor objects are sending audio samples that are given by a registered sender object to an auproc-capi connector, see auproc.new_audio_sender() and ljack/example08.lua.
