Perform an ioctl operation on the device.
The default implementation handles DIOC_GETPRIV, and otherwise returns -ENOTTY. Subclasses should call the default implementation for any command they do not handle themselves.
- Parameters
-
| filep | Pointer to the NuttX file structure. |
| cmd | The ioctl command value. |
| arg | The ioctl argument value. |
- Returns
- OK on success, or -errno otherwise.
Reimplemented from cdev::CDev.
