is the pointer to a ${/c/if/cpu_set_t:/name} object. When the directive
call is successful, the processor affinity set of the interrupt vector will
be stored in this object. A set bit in the processor set means that the
corresponding processor is in the processor affinity set of the interrupt
vector, otherwise the bit is cleared.
