.TH XkbAllocGeomColors __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbAllocGeomColors \- Allocate geometry colors
.SH SYNOPSIS
.HP
.B Status XkbAllocGeomColors
.BI "(\^XkbGeometryPtr " "geom" "\^,"
.BI "int " "num_needed" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- geom
geometry for which colors should be allocated
.TP
.I \- num_needed
number of new colors required
.SH DESCRIPTION
.LP
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
.I sz_*
but never touch
.I num_*
(unless there is an allocation failure, in which case they reset both
.I sz_*
and
.I 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.
.I XkbAllocGeomColors
allocates space for
.I num_needed
colors and adds them to the specified geometry
.I geom.
A color name is a string whose interpretation is not specified by Xkb. All other
geometry data structures refer to colors using their indices in this global list
or pointers to colors in this list.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadValue
An argument is out of range
