Also - does it work from the command line?  Do both mknod commands work? =

When you "ls -l /dev/test{1,2}" , what do you get?  What happens when =
you=20
"cat /dev/test1" or "echo > /dev/test1" ?

I'm sorry but this is a "copy to mail" error.
Here is the right code:

ret_val =3D system("mknod -m 777 /dev/test1 c 122 1");
ret_val =3D system("mknod -m 777 /dev/test2 c 122 2");

file_desc1 =3D open("/dev/test1", O_RDWR);
file_desc2 =3D open("/dev/test2", O_RDWR);
