-- Routines to build stream subprograms for composite types
with Exp_Tss; use Exp_Tss;
with Types; use Types;
package Exp_Strm is
function Build_Elementary_Input_Call (N : Node_Id) return Node_Id;
-- Build call to Read attribute function for elementary type. Also used
-- for Input attributes for elementary types with an appropriate extra
-- assignment statement. N is the attribute reference node.
function Build_Elementary_Write_Call (N : Node_Id) return Node_Id;
-- Build call to Write attribute function for elementary type. Also used
-- for Output attributes for elementary types (since the effect of the
-- two attributes is identical for elementary types). N is the attribute
-- reference node.
function Build_Stream_Attr_Profile
(Loc : Source_Ptr;
Typ : Entity_Id;
Nam : TSS_Name_Type) return List_Id;
-- Builds the parameter profile for the stream attribute identified by
-- the given name. This is used for the tagged case to build the spec
-- for the primitive operation.
-- The following routines build procedures and functions for stream
-- attributes applied to composite types. For each of these routines,
-- Loc is used to provide the location for the constructed subprogram
-- declaration. Typ is the base type to which the subprogram applies
-- (i.e. the base type of the stream attribute prefix). The returned
-- results are the declaration and name (entity) of the subprogram.

-- Called to build an array or record stream procedure. The first three
-- arguments are the same as Build_Record_Or_Elementary_Output_Procedure.
