Member Function Documentation
§ ioctl()
|
overridevirtual |
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.
The documentation for this class was generated from the following files:
- src/lib/drivers/accelerometer/PX4Accelerometer.hpp
- src/lib/drivers/accelerometer/PX4Accelerometer.cpp
