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
keyboard 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
