Line 1: Line 1:
In computing, ioctl (an abbreviation of input/output control) is a system call for device-specific input/output operations and other operations which cannot be expressed by regular file semantics. It takes a parameter specifying a request code; the effect of a call depends completely on the request code. Request codes are often device-specific. For instance, a CD-ROM device driver which can instruct a physical device to eject a disc would provide an ioctl request code to do so. Device-independent request codes are sometimes used to give usermode access to kernel functions which are only used by core system software or still under development.

= Finding the IOCTL handler address for a device in kernel =
# Find a string of the device name in kernel.
# There should be only two cross-references from function: make_dev and mutex_init. make_dev is the interesting one.
# The structure before the device string is what we want to look.
# Follow the structure then go to the very last offset of the structure. It is the handler function in charge of IOCTLs for that device.
