Hi PyPpl, For my current project I have a kernel device driver and a user-space application. This user-space application is already provided to me, and written in python. I have to extend this application with some addition features, which involves communicating with kernel device driver through ioctl() interface. I am fairly new with Python and not able to grok how to provide "op" in ioctl syntax - fcntl.ioctl (fd, op[, arg[, mutate_flag]]). Operations supported by device driver, through ioctl, are of the form: IOCTL_SET_MSG _IOR(MAGIC_NUMBER, 0, char*). It'd be great if some help can be provided about how to "encode" these operations in python to implement the desired functionality.
Regards Nitish
