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.
See also wikipedia page about IOCTL.

Description[edit | edit source]
int ioctl(int fd, unsigned long request, ...);
The ioctl() system call manipulates the underlying device parameters
of special files. In particular, many operating characteristics of
character special files (e.g., terminals) may be controlled with
ioctl() requests. The argument fd must be an open file descriptor.
The second argument is a device-dependent request code. The third
argument is an untyped pointer to memory. It's traditionally char
*argp (from the days before void * was valid C), and will be so named
for this discussion.
An ioctl() request has encoded in it whether the argument is an in
parameter or out parameter, and the size of the argument argp in
bytes. Macros and defines used in specifying an ioctl() request are
located in the file <sys/ioctl.h>.

Finding the IOCTL handler address for a device in kernel[edit | edit source]
- 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.
