XkbAllocGeomOverlayKeys(3) XKB FUNCTIONS XkbAllocGeomOverlayKeys(3)
NAME
XkbAllocGeomOverlayKeys - Allocate keys in an overlay row
SYNOPSIS
Status XkbAllocGeomOverlayKeys (XkbOverlayRowPtr row, int num_needed);
ARGUMENTS
- row 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 explic-
itly 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 Bad-
Value if a parameter is not as expected.
XkbAllocGeomOverlayKeys allocates num_needed keys and adds them to the
row. No initialization of the keys is done.
DIAGNOSTICS
BadAlloc Unable to allocate storage
BadValue An argument is out of range
