XkbFreeGeomOverlayRows(3)
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
