Section (3) sched_getcpu
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
returns a nonnegative CPU number. On error, −1 is
errno is set to
indicate the error.
This kernel does not implement getcpu(2).
For an explanation of the terms used in this section, see attributes(7).
cpu = sched_getcpu();
is equivalent to the following getcpu(2) call:
int c, s; s = getcpu(&c, NULL, NULL); cpu = (s == −1) ? s : c;
