NAME¶
XkbAllocGeomRows - Allocate rows in a section
SYNOPSIS¶
Status XkbAllocGeomRows (XkbSectionPtr
section, int num_needed);
ARGUMENTS¶
- - section
- 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.
XkbAllocGeomRows allocates
num_needed rows and adds them to the
section. No initialization of the rows is done.
DIAGNOSTICS¶
- BadAlloc
- Unable to allocate storage
- BadValue
- An argument is out of range
