+This function returns the information associated to a user heap vseg : vaddr and length.
  * If (x < X_SIZE) and (y < Y_SIZE), it return the heap associated to any task running in cluster(x,y). 
  * else, it return the heap associated to the calling task.
-It uses the global task index (CTX_GTID_ID, unique for each giet task) and the vspace index (CTX_VSID_ID), that are defined in the calling task context to find the vobj_id containing the heap. 
 Returns 0 if success, returns -1 if not found.
