nk ("nanokernel") is a runtime built on top of pthreads that implements
cooperative (non-preemptive) multithreading between cheap user threads and
one-off deferred procedure calls (DPCs). It supports message-passing between
these threads and deferred calls, and implements some other basic
synchronization such as semaphores/mutexes. It may coexist with other
pthreads-based code in the same process.
nk is built with CMake. Simply create a build directory, run cmake [src dir] there, and make. The nk_test binary will run unit tests.
