32 ioctl_list \- list of ioctl calls in Linux/i386 kernel
34 This is Ioctl List 1.3.27, a list of ioctl calls in Linux/i386 kernel
36 It contains 421 ioctls from
37 .IR </usr/include/{asm,linux}/*.h> .
38 For each ioctl, its numerical value, its name, and its argument
42 .I "const struct foo\ *"
43 means the argument is input to the kernel.
45 means the kernel outputs the argument.
46 If the kernel uses the argument for both input and output, this is
47 marked with \fI//\ I-O\fP.
49 Some ioctls take more arguments or return more values than a single
51 These are marked \fI//\ MORE\fP and documented further in a
54 This list is very incomplete.
56 .\" added two sections - aeb
57 Ioctl command values are 32-bit constants.
58 In principle these constants are completely arbitrary, but people have
59 tried to build some structure into them.
61 The old Linux situation was that of mostly 16-bit constants, where the
62 last byte is a serial number, and the preceding byte(s) give a type
63 indicating the driver.
64 Sometimes the major number was used: 0x03
71 one or more ASCII letters were used.
75 0x00005401, with 0x54 = \(aqT\(aq indicating the terminal driver, and
77 has value 0x00435906, with 0x43 0x59 = \(aqC\(aq \(aqY\(aq
78 indicating the cyclades driver.
80 Later (0.98p5) some more information was built into the number.
81 One has 2 direction bits
82 (00: none, 01: write, 10: read, 11: read/write)
83 followed by 14 size bits (giving the size of the argument),
84 followed by an 8-bit type (collecting the ioctls in groups
85 for a common purpose or a common driver), and an 8-bit
88 The macros describing this structure live in
93 .BR "{_IOR,_IOW,_IOWR}(type,nr,size)" .
97 misnomer here: this third argument is a data type.
99 Note that the size bits are very unreliable: in lots of cases
100 they are wrong, either because of buggy macros using
101 .IR sizeof(sizeof(struct)) ,
102 or because of legacy values.
104 Thus, it seems that the new structure only gave disadvantages:
105 it does not help in checking, but it causes varying values
106 for the various architectures.
108 Decent ioctls return 0 on success and \-1 on error, while
109 any output value is stored via the argument.
111 quite a few ioctls in fact return an output value.

771 Some ioctl's take a pointer to a structure which contains additional
773 These are documented here in alphabetical order.
776 takes an input pointer
777 .IR "const struct cdrom_read_audio\ *" .
780 field points to an output buffer of length
781 .IR "nframes\ * CD_FRAMESIZE_RAW" .
783 .BR CDROMREADCOOKED ,
788 take an input pointer
789 .IR "const struct cdrom_msf\ *" .
790 They use the same pointer as an output pointer to
792 The length varies by request.
795 most drivers use CD_FRAMESIZE, but the Optics Storage
796 driver uses OPT_BLOCKSIZE instead (both have the numerical value
800 CDROMREADCOOKED char [CD_FRAMESIZE]
801 CDROMREADMODE1 char [CD_FRAMESIZE or OPT_BLOCKSIZE]
802 CDROMREADMODE2 char [CD_FRAMESIZE_RAW0]
803 CDROMREADRAW char [CD_FRAMESIZE_RAW]
808 .BR EQL_GETSLAVECFG ,
809 .BR EQL_SETSLAVECFG ,
810 .BR EQL_GETMASTERCFG ,
814 .IR "struct ifreq\ *" .
817 field is a pointer to another structure as follows:
820 EQL_ENSLAVE const struct slaving_request *
821 EQL_EMANCIPATE const struct slaving_request *
822 EQL_GETSLAVECFG struct slave_config * // I-O

824 EQL_GETMASTERCFG struct master_config *
825 EQL_SETMASTERCFG const struct master_config *
830 .IR "struct floppy raw_cmd\ *" .
832 .I flags & FD_RAW_WRITE
835 points to an input buffer of length
838 .I flags & FD_RAW_READ
841 points to an output buffer of length
848 .I struct console_font_desc\ *
850 .IR "const struct console_font_desc\ *" ,
853 points to a buffer of
854 .IR "char [charcount]" .
855 This is an output buffer for
857 and an input buffer for
864 .I "struct unimapdesc\ *"
866 .IR "const struct unimapdesc\ *" ,
869 points to a buffer of
870 .IR "struct unipair [entry_ct]" .
871 This is an output buffer for
873 and an input buffer for
876 KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to
878 They are essentially alternate interfaces to 'ioperm'.
883 enable or disable memory mappings or I/O port access.
884 They are not implemented in the kernel.
886 .B SCSI_IOCTL_PROBE_HOST
887 takes an input pointer
890 It uses the same pointer as an output pointer to a
892 buffer of this length.
897 take an input pointer whose type depends on
901 Most protocols const struct rtentry *
902 AX.25 const struct ax25_route *
903 NET/ROM const struct nr_route_struct *
908 .IR "struct ifconf\ *" .
911 field points to a buffer of length
913 bytes, into which the kernel writes a list of type
914 .IR "struct ifreq []" .
917 takes an input pointer whose type depends on the protocol:
920 Most protocols const struct ifreq *
921 AX.25 const char [AX25_ADDR_LEN]
926 .IR "const char\ *" .
927 It uses this to distinguish several
928 independent subcases.
