The lib directory contains the user-library which translates the gpiolib API into ioctl calls to the driver, and the app program is a simple program which uses the library. You can view the source vie websvn as well: <http://websvn.hylands.org/filedetails.php?repname=Projects&path=/linux/gpio/module/user-gpio-drv.c&rev=0&sc=0> -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
