XkbAllocGeomKeys(3) XKB FUNCTIONS XkbAllocGeomKeys(3)NAME
XkbAllocGeomKeys - Allocate space for an arbitrary number of keys to a row
SYNOPSIS
Status XkbAllocGeomKeys ( row, num_needed )
XkbRowPtr row;
int num_needed;
ARGUMENTS
- row row to which keys should be allocated
- num_needed
number of new keys required
DESCRIPTION
Xkb provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify key-
board geometries. Note that these functions merely allocate space for the new element(s), and it is up to you to fill in the values
explicitly in your code. These allocation functions increase sz_* but never touch num_* (unless there is an allocation failure, in which
case they reset both sz_* and num_* to zero). These functions return Success if they succeed, BadAlloc if they are not able to allocate
space, or BadValue if a parameter is not as expected.
XkbAllocGeomKeys allocates num_needed keys and adds them to the row. No initialization of the keys is done.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range

XkbAllocGeomSections(3) XKB FUNCTIONS XkbAllocGeomSections(3)NAME
XkbAllocGeomSections - Allocate geometry sections
SYNOPSIS
Status XkbAllocGeomSections ( geom, num_needed )
XkbGeometryPtr geom;
int num_needed;
ARGUMENTS
- geom geometry for which sections should be allocated
- num_needed
number of new sections required

XkbAllocGeomSections allocates num_needed sections and adds them to the geometry geom. No initialization of the sections is done.
To free geometry sections, use XkbFreeGeomSections.

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
