/*******************************************************************************

 $Function:    	wap_offset_table

 $Description:	The data structure that is transmitted in the event will have pointers
 				that point to blocks of data (e.g. text).  These blocks are bundled
 				together with the data structure itself and sent, but on receipt the
 				pointers are no longer correct.  The offset table stores the *position*
 				of these pointers in the data structure, relative to the base address
 				of the data structure itself.  This permits the decoder to correctly
 				reassign these pointers.

 $Returns:		None.

 $Arguments:	struct_size  - pointer to ushort variable that holds length of structure
 				in bytes
