An ioctl on the drivers device node, eg:
fd = open("/dev/mydriver", O_RDWR);
ioctl(fd, MYDRIVER_FOO_ACTION, &myfooadata);
Is this also available for modules which are not drivers?
You have to create and program this yourself it isn't done automatically
for you.
Any module can do this if the code in the module has a device node and
supports the open and ioctl entry points.
