FIFO write and read

Can someone help me to write this program in C in QNX?

Using the FIFO queues write a simple communication system consisting of programs write and read. The program write the parameters given strings enclosed in single quotes. These strings are written to the FIFO file. Reads the program read them from there. Programs should behave as in the following example.

$write �write1'
$read
read 1
$

I dont know how to do it, but need this program to pass an exam ;(
