conio.h functions not supported under qnx6   
In the process of porting code over from qnx4 to qnx6 there are many function that are no longer supported.  Many I can 
write my own function to replace to old ones, but for function such as getch() and kbhit() the migration tool suggest 
using read() and tcischars().  How do you use these function on stdin?  The seem to be designed for file pointer and not
 a device.

Can anyone tell me if there are any replacement function within qnx6 that work the same as getch() and kbhit()?

You will need to set stdin to be unbuffered (use setvbuf) and you will need
to set STDIN_FILENO to be non blocking.

Then you can use read() and tcischars()
