XkbAllocGeomOverlayKeys(3) XKB FUNCTIONS XkbAllocGeomOverlayKeys(3)NAME
XkbAllocGeomOverlayKeys - Allocate keys in an overlay row
SYNOPSIS
Status XkbAllocGeomOverlayKeys ( row, num_needed )
XkbRowPtr row;
int num_needed;
ARGUMENTS
- row section for which rows should be allocated
- num_needed
number of new rows 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 explic-
itly 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.
XkbAllocGeomOverlayKeys 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

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
