.TH XkbAllocGeomKeys __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbAllocGeomKeys \- Allocate space for an arbitrary number of keys to a row
.SH SYNOPSIS
.HP
.B Status XkbAllocGeomKeys
.BI "(\^XkbRowPtr " "row" "\^,"
.BI "int " "num_needed" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- row
row to which keys should be allocated
.TP
.I \- num_needed
number of new keys required
.SH DESCRIPTION
.LP
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
.I sz_*
but never touch
.I num_*
(unless there is an allocation failure, in which case they reset both
.I sz_*
and
.I 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.
.I XkbAllocGeomKeys
allocates
.I num_needed
keys and adds them to the
.I row.
No initialization of the keys is done.
.SH DIAGNOSTICS
.TP 15
.B BadAlloc
Unable to allocate storage
.TP 15
.B BadValue
An argument is out of range
