# struct\_ccw\_device(9)

channel attached device

## NAME

struct\_ccw\_device - channel attached device

## SYNOPSIS

```
struct ccw_device {
  spinlock_t * ccwlock;
  struct ccw_device_id id;
  struct ccw_driver * drv;
  struct device dev;
  int online;
  void (* handler) (struct ccw_device *, unsigned long, struct irb *);
};
```

## MEMBERS

ccwlock

pointer to device lock

id

id of this device

drv

ccw driver for this device

dev

online

## DESCRIPTION

*handler* is a member of the device rather than the driver since a driver can have different interrupt handlers for different ccw devices (multi-subchannel drivers).
