TWINE

Thread and Worker INterface for Elk Audio OS

Support library for managing realtime threads and worker pools

Copyright Copyright 2017-2023 Elk Audio AB, Stockholm, Sweden.

Usage

To include twine in a CMake based project the lines below needs to be added to the projects CMake configuration. Further build options can be found in twine/CMakeLists.txt add_subdirectory(twine) target_link_libraries(project PRIVATE twine)

This will also export the necessary include folders so that the twine header file can then be included into source files with:

#include "twine/twine.h

By default, the target twine is a shared library. A static library target is also generated and can be linked instead by using twine_objlib.

CMake build options

Option Value Notes
TWINE_WITH_XENOMAI on / off Build with Xenomai realtime thread support
TWINE_WITH_TESTS on / off Build and run unit tests
TWINE_BUILD_WITH_APPLE_COREAUDIO on / off Build with CoreAudio support on macOS. This is needed to support apple silicon real-time thread workgroups

On macOS, Apple CoreAudio is on by default - switching it off will significantly affect performance on Apple Silicon, since CoreAudio is needed for joining thread workgroups.
