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
