# NAME

`interrupt_distribute` —
assign an interrupt to a CPU

# SYNOPSIS

`#include <sys/interrupt.h>`

int
`interrupt_distribute`(void *ich, const kcpuset_t *newset, kcpuset_t *oldset);

# DESCRIPTION

The `interrupt_distribute` function exists to assign an interrupt to a CPU.

If a driver (or the other kernel component) wishes to assign an interrupt to a CPU, it should pass an interrupt handler such as the return value of `pci_intr_establish`() as ich argument, and it should pass the kcpuset to which it should be assigned as newset. To get the previous value, pass a non-`NULL` value to oldset.
