XkbAllocGeomKeys(3)						   XKB FUNCTIONS					       XkbAllocGeomKeys(3)

NAME
       XkbAllocGeomKeys - Allocate space for an arbitrary number of keys to a row

SYNOPSIS
       Status XkbAllocGeomKeys (XkbRowPtr row, int num_needed);

ARGUMENTS
       - row  row to which keys should be allocated

       - num_needed
	      number of new keys required

DESCRIPTION
       Xkb  provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify key-
       board 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.

       XkbAllocGeomKeys allocates num_needed keys and adds them to the row.  No initialization of the keys is done.

DIAGNOSTICS
       BadAlloc       Unable to allocate storage

       BadValue       An argument is out of range
