It contains 421 ioctls from /usr/include/{asm,linux}/*.h. +For each ioctl, its numerical value, its name, and its argument +type are given. +.PP +An argument type of 'const struct foo *' means the argument is input +to the kernel. 'struct foo *' means the kernel outputs the argument. +If the kernel uses the argument for both input and output, this is +marked with // I-O. +.PP +Some ioctls take more arguments or return more values than a single +structure. These are marked // MORE and documented further in a +separate section. +.PP +This list is very incomplete. +Please e-mail changes and comments to <mec@duracef.shout.net>. + +.SH "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. +.LP +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 HDIO_* ioctls, 0x06 for the LP* ioctls. And sometimes +one or more ASCII letters were used. For example, TCGETS has value +0x00005401, with 0x54 = 'T' indicating the terminal driver, and +CYGETTIMEOUT has value 0x00435906, with 0x43 0x59 = 'C' 'Y' +indicating the cyclades driver. +.LP +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. +.LP +The macros describing this structure live in <asm/ioctl.h> +and are _IO(type,nr) and {_IOR,_IOW,_IOWR}(type,nr,size). +They use sizeof(size) so that size is a +misnomer here - this third parameter is a data type. +.LP +Note that the size bits are very unreliable - in lots of cases +they are wrong - either because of buggy macros using +sizeof(sizeof(struct)), or because of legacy values. +.LP +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. + +.SH "RETURN VALUE" +Decent ioctls return 0 on success and \-1 on error, while +any output value is stored via the argument. However, +quite a few ioctls in fact return an output value. +This is not yet indicated below. + +.nf + +// Main table. + +// <include/asm-i386/socket.h> +0x00008901 FIOSETOWN const int * +0x00008902
