XkbAllocGeomColors(3)			  XKB FUNCTIONS 		    XkbAllocGeomColors(3)

NAME
       XkbAllocGeomColors - Allocate geometry colors

SYNOPSIS
       Status XkbAllocGeomColors (XkbGeometryPtr geom, int num_needed);

ARGUMENTS
       - geom geometry for which colors should be allocated

       - num_needed
	      number of new colors required

DESCRIPTION
       Xkb provides a number of functions to allocate and free subcomponents of a keyboard geome-
       try. Use these functions to create or modify keyboard geometries.  Note that  these  func-
       tions  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.

       XkbAllocGeomColors  allocates  space  for num_needed colors and adds them to the specified
       geometry 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.

DIAGNOSTICS
       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
