XkbFreeGeomOverlays - Man Page

Free rows in a section


void XkbFreeGeomOverlays (XkbSectionPtr section, int first, int count, Bool free_all);


- section

section in which overlays should be freed

- first

first overlay to be freed

- count

number of overlays to be freed

- free_all

True => all overlays are freed


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.

If free_all is True, all overlays are freed regardless of the value of first and count. Otherwise, the number of overlays specified by count are freed, beginning with the overlay specified by first in the specified section.

Return Values


The XkbFreeGeomOverlays functions returns Success if there are no allocation or  argument errors.



Unable to allocate storage


An argument is out of range
