XkbAddGeomOutline(3) XKB FUNCTIONS XkbAddGeomOutline(3)NAME
XkbAddGeomOutline - Add one outline to an existing shape
SYNOPSIS
XkbOutlinePtr XkbAddGeomOutline ( shape, sz_points )
XkbShapePtr shape;
int sz_points;
ARGUMENTS
- shape
shape to be updated
- sz_points
number of points to be reserved
DESCRIPTION
Xkb provides functions to add a single new element to the top-level keyboard geometry. In each case the num_ * fields of the corresponding
structure is incremented by 1. These functions do not change sz_* unless there is no more room in the array. Some of these functions fill
in the values of the element's structure from the arguments. For other functions, you must explicitly write code to fill the structure's
elements.
The top-level geometry description includes a list of geometry properties. A geometry property associates an arbitrary string with an
equally arbitrary name. Programs that display images of keyboards can use geometry properties as hints, but they are not interpreted by
Xkb. No other geometry structures refer to geometry properties.
An outline consists of an arbitrary number of points. XkbAddGeomOutline adds an outline to the specified shape by reserving sz_points
points for it. The new outline is allocated and zeroed. XkbAddGeomOutline returns NULL if any of the parameters is empty or if it was not
able to allocate space. To allocate space for an arbitrary number of outlines to a shape, use XkbAllocGeomOutlines.
STRUCTURES
typedef struct _XkbOutline {
unsigned short num_points; /* number of points in the outline */
unsigned short sz_points; /* size of the points array */
unsigned short corner_radius; /* draw corners as circles with this radius */
XkbPointPtr points; /* array of points defining the outline */
} XkbOutlineRec, *XkbOutlinePtr;

XkbAddGeomKey(3) XKB FUNCTIONS XkbAddGeomKey(3)NAME
XkbAddGeomKey - Add one key at the end of an existing row of keys
SYNOPSIS
XkbKeyPtr XkbAddGeomKey (XkbRowPtr row);
ARGUMENTS
- row row to be updated
DESCRIPTION
Xkb provides functions to add a single new element to the top-level keyboard geometry. In each case the num_ * fields of the corresponding
structure is incremented by 1. These functions do not change sz_* unless there is no more room in the array. Some of these functions fill

equally arbitrary name. Programs that display images of keyboards can use geometry properties as hints, but they are not interpreted by
Xkb. No other geometry structures refer to geometry properties.
Keys are grouped into rows. XkbAddGeomKey adds one key to the end of the specified row. The key is allocated and zeroed. XkbAddGeomKey
returns NULL if row is empty or if it was not able to allocate space for the key. To allocate space for an arbitrary number of keys to a
row, use XkbAllocGeomKeys.
STRUCTURES
typedef struct _XkbKey { /* key in a row */
XkbKeyNameRec name; /* key name */
short gap; /* gap in mm/10 from previous key in row */
unsigned char shape_ndx; /* index of shape for key */
unsigned char color_ndx; /* index of color for key body */
} XkbKeyRec, *XkbKeyPtr;

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
