suitable IOCTL error code when device is in state IOCTL cannot performed
Subject says it all. Which one error value is most suitable / generic ?
Here are few ones I found which could be possible:
#define EPERM 1 /* Operation not permitted */ #define EAGAIN 11 /* Try again */ #define EACCES 13 /* Permission denied */ #define EBUSY 16 /* Device or resource busy */ #define ENODATA 61 /* No data available */
#define ECANCELED 125 /* Operation Canceled */

IMHO, EAGAIN, EBUSY or ENODATA are the most pertinent ones.
