NAME
pthread_curcpu_np -- get current CPU identifier
SYNOPSIS

DESCRIPTION
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.
RETURN VALUES
The pthread_curcpu_np() function returns the integer identifier of the CPU which is currently running the calling thread.
COMPATIBILITY
The pthread_curcpu_np() function is a non-standard extension.
