man sched_getaffinity says sched.h :-)

from my fedora 6 (with all latest updates) /usr/include/sched.h:
/* Get the CPU affinity for a task */
extern int sched_getaffinity (__pid_t __pid, size_t __cpusetsize,
                              cpu_set_t *__cpuset) __THROW;

$ rpm -q --whatprovides /usr/include/sched.h
glibc-headers-2.5-18.fc6
