SYNTAX

#include <rtapi_device.h>
struct rtapi_device;
int rtapi_dev_set_name(struct rtapi_device* dev, const char* name, ...);
int rtapi_device_register(struct rtapi_device* dev);
int rtapi_device_unregister(struct rtapi_device* dev);

DESCRIPTION

In kernel space, each `rtapi_`xxx or `RTAPI_`XXX identifier is mapped to the underlying kernel functionality, if available.

In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation—​possibly with reduced functionality—​is provided. (For example, the userspace implementation for rtapi_device_register always succeeds)

REALTIME CONSIDERATIONS

Typically, these functions may be called from realtime init/cleanup code.

RETURN VALUE

As in Linux.
