| PIO_UNIMAPCLR |
Clear table, possibly advise hash algorithm.
argp points to a
struct unimapinit {
u short advised hashsize; /* 0 if no opinion */
u short advised hashstep; /* 0 if no opinion */
u short advised hashlevel; /* 0 if no opinion */
};
(Since 1.1.92.)

| KDGKBMODE |
Gets current keyboard mode. argp points to a
long, which is set to one of these:K_RAW 0x00 K_XLATE 0x01 K_MEDIUMRAW 0x02 K_UNICODE 0x03 |
| KDSKBMODE | Sets current keyboard mode. argp is a long equal to one of the above values. |
| KDGKBMETA |
Gets meta key handling mode. argp points to a long which is set to one of these:K_METABIT 0x03 Set high order bit K_ESCPREFIX 0x04 Escape prefix |
| KDSKBMETA | Sets meta key handling mode. argp is a long equal to one of the preceding values. |
| KDGKBENT |
Gets one entry in key translation table (keycode to action code).
argp points to a
struct kbentry {
u_char kb_table;
u_char kb_index;
u_short kb_value;
};
|
| with the first two members filled in: kb_table selects the key table (0 <= kb_table <MAX_NR_KEYMAPS), and kb_index is the keycode (0 <= kb index <NR_KEYS). kb_value is set to the corresponding action code, or K_HOLE if there is no such key, or K_NOSUCHMAP if kb_table is invalid. | |
| KDSKBENT | Sets one entry in translation table. argp points to a struct kbentry. |
| KDGKBSENT |
Gets one function key string. argp points to a
struct kbsentry {
u_char kb_func;
u_char kb_string[512];
;
|
| kb_string is set to the (NULL-terminated) string corresponding to the kb_functh function key action code. | |
| KDSKBSENT | Sets one function key string entry. argp points to a struct kbsentry. |
| KDGKBDIACR |
Read kernel accent table. argp points to a
struct kbdiacrs {
unsigned int kb_cnt;
struct kbdiacr kbdiacr[256];
};
|
| where kb_cnt is the number of entries in the array, each of which is a struct kbdiacr { u_char diacr, base, result ;}; | |
| KDGETKEYCODE |
Read kernel keycode table entry (scan code to keycode).
argp points to a
struct kbkeycode { unsigned int scancode, keycode; }; keycode is set to correspond to the given scancode.(89<=scancode <= 255 only. For 1 <= scancode <= 88, keycode==scancode.) (Since 1.1.63.) |
| KDSETKEYCODE | Write kernel keycode table entry. argp points to struct kbkeycode. (Since 1.1.63.) |

| KDSIGACCEPT | The calling process indicates its willingness to accept the signal argp when it is generated by pressing an appropriate key combination. (1 <= argp <=NSIG). (See spawn_console() in linux/drivers/char/keyboard.c.) |
| VT_OPENQRY | Returns the first available (nonopened) console. argp points to an int that is set to the number of the vt (1 <= *argp <=MAX_NR_CONSOLES). |
| VT_GETMODE |
Get mode of active vt. argp points to a
struct vt mode {
char mode;/*vtmode*/
char waitv; /* if set, hang on writes if not active */
short relsig; /* signal to raise on release req */
short acqsig; /* signal to raise on acquisition */
short frsig; /* unused (set to 0) */
};
|
mode is set to one of these values:VT_AUTO Auto vt switching VT_PROCESS Process controls switching VT_ACKACQ Acknowledge switch | |
| VT_SETMODE | Set mode of active vt. argp points to a struct vt_mode. |
| VT_GETSTATE | Get global vt state info. argp points to a |
struct vt_stat {
ushort v_active; /* active vt */
ushort v_signal;/*signalto send*/
ushort v_state;/*vtbitmask*/
};
| |
| For each vt in use, the corresponding bit in the v state member is set. (Kernels 1.0 through 1.1.92.) | |
| VT_RELDISP | Release a display. |
| VT_ACTIVATE | Switch to vt argp (1 <= argp <=MAX_NR_CONSOLES). |
| VT_WAITACTIVE | Wait until vt argp has been activated. |
| VT_DISALLOCATE | Deallocate the memory associated with vt argp. (Since 1.1.54.) |
| VT_RESIZE | Set the kernel's idea of screensize. argp points to a |
struct vt_sizes {
ushort v_rows;/*#rows*/
ushort v_cols;/*#columns */
ushort v_scrollsize; /* no longer used */
};
| |
| Note that this does not change the video mode. See resizecons(8). (Since 1.1.54.) | |
| VT_RESIZEX | Set the kernel's idea of various screen parameters. argp points to a |
| struct vt_consize { | |
| ushort v_rows; /* number of rows */ | |
| ushort v_cols; /* number of columns */ | |
| ushort v_vlin; /* number of pixel rows on screen */ | |
| ushort v_clin; /* number of pixel rows per character */ | |
| ushort v_vcol; /* number of pixel columns on screen */ | |
| ushort v_ccol; /* number of pixel columns per character */ | |
| }; | Any parameter may be set to zero, indicating no change, but if multiple parameters are set, they must be self-consistent. Note that this does not change the video mode. See resizecons(8). (Since 1.3.3.) |
