XkbAddGeomRow(3) XKB FUNCTIONS XkbAddGeomRow(3)
NAME
XkbAddGeomRow - Add a row to a section
SYNOPSIS
XkbRowPtr XkbAddGeomRow (XkbSectionPtr section, int sz_keys);
ARGUMENTS
section
section to be updated
sz_keys
number of keys 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.
One of the components of a keyboard geometry section is one or more rows
of keys. XkbAddGeomRow adds one row to the specified section. The newly
created row contains space for the number of keys specified in sz_keys.
They are allocated and zeroed, but otherwise uninitialized.
XkbAddGeomRow returns NULL if any of the parameters is empty or if it was
not able to allocate space for the row. To allocate space for an
arbitrary number of rows to a section, use the XkbAllocGeomRows function.
