PTHREAD_CURCPU_NP(3) Library Functions Manual PTHREAD_CURCPU_NP(3)
pthread_curcpu_np -- get current CPU identifier
The pthread_curcpu_np() function provides a way for a thread to know
which CPU it's currently running on.
Note that, unless the thread is bound to a specific CPU, the result might
be already stale when the function returns. However, it still can be
useful as a hint to achieve better CPU locality.
The pthread_curcpu_np() function returns the integer identifier of the
CPU which is currently running the calling thread.
The pthread_curcpu_np() function is a non-standard extension.
