  22 /*  FUNCTION
  23         Inserts a custom purge hook for the given local context item.
  24         The purge hook will be freed when the system wants to delete a local
  25         context item.
  26
  27     INPUTS
  28         localItem  -  pointer to a local context item.
  29         purgeHook  -  pointer to a hook sructure initialized with the purge function.
  30
  31     RESULT
  32
  33     NOTES
  34         The purgehook must call FreeLocalItem() on the local context item after
  35         doing its own resource freeing.
