xkballocgeomoverlayrows
XkbAllocGeomOverlayRows(3) XKB FUNCTIONS XkbAllocGeomOverlayRows(3)
NAME
XkbAllocGeomOverlayRows - Allocate rows in a overlay
SYNOPSIS
Status XkbAllocGeomOverlayRows (XkbOverlayPtr overlay, int num_needed);
ARGUMENTS
- overlay
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
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.
XkbAllocGeomOverlayRows allocates num_needed rows and adds them to the overlay. No initialization of the rows is done.
To free rows in an overlay, use XkbFreeGeomOverlayRows.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range
