Yet another newbie question. 

I have got latest debian image on my beagle bone black.
uname - r output: 4.9.45-ti-r57

and I noticed various gpio directory in /sys/class/gpio

when I tried
echo 69 > unexport 
it gave me permission denied.
so I changed the permission of unexport file to be 666

and now when I try to use the same command it gives me an error: 
-bash: echo: write error: Invalid argument

Can anyone please help...

Ultimately I want to develop a C++ project to toggle LED which is connected 
to one of the pins...

Any help regarding this matter is deeply appreciated.
