In particular, many operating characteristics of character special files

The second argument is a device-dependent request code.

The third argument is an untyped pointer to memory.

|
.SS ioctl structure
|
|
|
|
|
.\" added two sections - aeb
|
|
|
|
|
Ioctl command values are 32-bit constants.
|
|
|
|
|
In principle these constants are completely arbitrary, but people have
|
|
|
|
|
tried to build some structure into them.
|
|
|
|
|
.PP
|
|
|
|
|
The old Linux situation was that of mostly 16-bit constants, where the
|
|
|
|
|
last byte is a serial number, and the preceding byte(s) give a type
|
|
|
|
|
indicating the driver.
|
|
|
|
|
Sometimes the major number was used: 0x03
|
|
|
|
|
for the
|
|
|
|
|
.B HDIO_*
|
|
|
|
|
ioctls, 0x06 for the
|
|
|
|
|
.B LP*
|
|
|
|
|
ioctls.
|
|
|
|
|
And sometimes
|
|
|
|
|
one or more ASCII letters were used.
|
|
|
|
|
For example,
|
|
|
|
|
.B TCGETS
|
|
|
|
|
has value
|
|
|
|
|
0x00005401, with 0x54 = \(aqT\(aq indicating the terminal driver, and
|
|
|
|
|
.B CYGETTIMEOUT
|
|
|
|
|
has value 0x00435906, with 0x43 0x59 = \(aqC\(aq \(aqY\(aq
|
|
|
|
|
indicating the cyclades driver.
|
|
|
|
|
.PP
|
|
|
|
|
Later (0.98p5) some more information was built into the number.
|
|
|
|
|
One has 2 direction bits
|
|
|
|
|
(00: none, 01: write, 10: read, 11: read/write)
|
|
|
|
|
followed by 14 size bits (giving the size of the argument),
|
|
|
|
|
followed by an 8-bit type (collecting the ioctls in groups
|
|
|
|
|
for a common purpose or a common driver), and an 8-bit
|
|
|
|
|
serial number.
|
|
|
|
|
.PP
|
|
|
|
|
The macros describing this structure live in
|
|
|
|
|
.I <asm/ioctl.h>
|
|
|
|
|
and are
|
|
|
|
|
.B _IO(type,nr)
|
|
|
|
|
and
|
|
|
|
|
.BR "{_IOR,_IOW,_IOWR}(type,nr,size)" .
|
|
|
|
|
They use
|
|
|
|
|
.I sizeof(size)
|
|
|
|
|
so that size is a
|
|
|
|
|
misnomer here: this third argument is a data type.
|
|
|
|
|
.PP
|
|
|
|
|
Note that the size bits are very unreliable: in lots of cases
|
|
|
|
|
they are wrong, either because of buggy macros using
|
|
|
|
|
.IR sizeof(sizeof(struct)) ,
|
|
|
|
|
or because of legacy values.
|
|
|
|
|
.PP
|
|
|
|
|
Thus, it seems that the new structure only gave disadvantages:
|
|
|
|
|
it does not help in checking, but it causes varying values
|
|
|
|
|
for the various architectures.
