   type:         longword (unsigned)
   access:       modify
   mechanism:    by reference
   User context information to be passed to other user routines. The
   context argument is the address of a longword that contains user
   context information.

   You should specify the value of this argument as 0 in the first
   of a sequence of calls to MAIL routines. In following calls, you
   should specify the user context value returned by the previous
   routine.

   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Item list specifying options for the routine. This routine does
   not use the in_item_list argument.
 

out_item_list

   OpenVMS usage:itmlst_3
   type:         longword
   access:       write only
   mechanism:    by reference
   Item list specifying the information you want the routine to
   return. The out_item_list argument is the address of a list of
   item descriptors, each of which describes an item of information.
   The list of item descriptors is terminated by longword value of
   0.
