I would use ENOTTY, or maybe ENODEV.  The name might be ENOTTY but the  
strerror() text is appropriate.

 From http://www.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_03.html#tag_02_03

[ENOTTY] Inappropriate I/O control operation. A control function has  
been attempted for a file or special file for which the operation is  
inappropriate.

[ENODEV] No such device. An attempt was made to apply an inappropriate  
function to a device; for example, trying to read a write-only device  
such as a printer.
