 * Purpose: This header-file defines the SUA Transaction Control Block(TCB) 
 *          pool functions for(needed for SUA connection oriented):
 *          - initialising a single TCB
 *          - initialising the TCB pool
 *          - allocate a TCB
 *          - get a TCB
 *          - release a TCB
 *          And for the Saved SUA msg queue pool
 *          - add SUA msg to queue
 *          - get sua msg from queue
 *          - release the SUA msg from the queue
