I’m writing Device Firmware Upgrade (DFU) protocol application driver
for the existing “devu-ohci” USB driver in QNX. The DFU protocol
application driver requires sending an IOCTL command to the driver
each time a control code (makes the device to perform a specific
operation, such as readData / write Data) is sent to the driver.
Is there any function in QNX which allows me to send the IOCTL command
along with the control codes
