XkbAllocGeomPoints(3)				    XKB FUNCTIONS				XkbAllocGeomPoints(3)

NAME
XkbAllocGeomPoints - Allocate points in an outline
SYNOPSIS
Status XkbAllocGeomPoints (XkbOutlinePtr outline, int num_needed);
ARGUMENTS
- outline outline for which points should be allocated - num_needed number of new points required
DESCRIPTION
Xkb provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these func- tions 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. XkbAllocGeomPoints allocates space for num_needed points in the specified outline. The points are not ini- tialized.
DIAGNOSTICS
BadAlloc Unable to allocate storage BadValue An argument is out of range X Version 11 libX11 1.6.0 XkbAllocGeomPoints(3)
