XkbAllocGeomOutlines(3) 			    XKB FUNCTIONS			      XkbAllocGeomOutlines(3)

NAME
XkbAllocGeomOutlines - Allocate space for an arbitrary number of outlines to a shape
SYNOPSIS
Status XkbAllocGeomOutlines (XkbShapePtr shape, int num_needed);
ARGUMENTS
- shape shape for which outlines should be allocated - num_needed number of new outlines 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. XkbAllocGeomOutlines allocates space for num_needed outlines in the specified shape. The outlines are not initialized. To free geometry outlines, use XkbFreeGeomOutlines.
DIAGNOSTICS
BadAlloc Unable to allocate storage BadValue An argument is out of range
