XkbAllocGeomKeys(3) XKB FUNCTIONS XkbAllocGeomKeys(3)
NAME
XkbAllocGeomKeys - Allocate space for an arbitrary number of keys to a
row
SYNOPSIS
Status XkbAllocGeomKeys (XkbRowPtr row, int num_needed);
ARGUMENTS
row row to which keys should be allocated
num_needed
number of new keys 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.
XkbAllocGeomKeys 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
