# XkbFreeGeomOverlayRows(3)

Free rows in an overlay

## NAME

XkbFreeGeomOverlayRows - Free rows in an overlay

## SYNOPSIS

**void XkbFreeGeomOverlayRows** **(XkbSectionPtr** *overlay***,** **int** *first***,** **int** *count***,** **Bool** *free\_all***);**

## ARGUMENTS

- *overlay*

  section in which rows should be freed

- *first*

  first row to be freed

- *count*

  number of rows to be freed

- *free\_all*

  True =\> all rows are freed

## DESCRIPTION

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 rows are freed regardless of the value of *first* and *count.* Otherwise, the number of rows specified by *count* are freed, beginning with the row specified by *first* in the specified overlay.

## RETURN VALUES

- Success

  The XkbFreeGeomOverlayRows function returns Success if there are no allocation or argument errors.

## DIAGNOSTICS

- **BadAlloc**

  Unable to allocate storage

- **BadValue**

  An argument is out of range
