XkbAllocKeyboard(3) XKB FUNCTIONS XkbAllocKeyboard(3)NAME
XkbAllocKeyboard - Creates a keyboard description from scratch
SYNOPSIS
XkbDescRec XkbAllocKeyboard (void);
DESCRIPTION
Applications seldom need to directly allocate a keyboard description; calling XkbGetKeyboard usually suffices. In the event you need to
create a keyboard description from scratch, however, use XkbAllocKeyboard rather than directly calling malloc.
If XkbAllocKeyboard fails to allocate the keyboard description, it returns NULL. Otherwise, it returns a pointer to an empty keyboard
description structure. The device_spec field will have been initialized to XkbUseCoreKbd. You may then either fill in the structure compo-
nents or use Xkb functions to obtain values for the structure components from a keyboard device.

XkbAllocGeometry(3) XKB FUNCTIONS XkbAllocGeometry(3)NAME
XkbAllocGeometry - Allocate an entire geometry
SYNOPSIS
Status XkbAllocGeometry (XkbDescPtr xkb, XkbGeometrySizesPtr sizes);
ARGUMENTS
- xkb keyboard description for which geometry is to be allocated
- sizes
initial sizes for all geometry components
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.
XkbAllocGeometry allocates a keyboard geometry and adds it to the keyboard description specified by xkb. The keyboard description should
be obtained via the XkbGetKeyboard or XkbAllocKeyboard functions. The sizes parameter specifies the number of elements to be reserved for
the subcomponents of the keyboard geometry and can be zero or more. These subcomponents include the properties, colors, shapes, sections,
and doodads.
To free an entire geometry, use XkbFreeGeometry.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range
