sched_getcpu - determine CPU on which the calling thread is running
sched_getcpu() returns the number of the CPU on which the calling thread is currently executing.
On success, sched_getcpu() returns a nonnegative CPU number. On error, -1 is returned and
errno is set to indicate the error.
This kernel does not implement getcpu(2).
This function is available since glibc 2.6.
sched_getcpu() is glibc-specific.
cpu = sched_getcpu();
is equivalent to the following getcpu(2) call:
int c, s; s = getcpu(&c, NULL, NULL); cpu = (s == -1) ? s : c;
