How to register Specialix card driver in QNX

Which API in Qnx is used to register the char device driver .please help me…

What do you mean by “register the char device driver”? A generic char device driver is a process. Once started, it becomes visible by taking control of some name space, ie. /dev/par. Maybe that is what you mean by registering?

how to install the driver

just run it :stuck_out_tongue:
its a mere process as any other process

If you want to run it every time the machine start, add it to /etc/rc.d/rc.local.

If it’s a driver for some sort of PCI device, you could edit the enum database to add your device to the list.

It implies that you have a QNX driver for your device or your device is supported by an existing QNX driver.
