That depends on what are going to achieve. Translating the above literally:

[ with Ada.Text_IO.Text_Streams;
  use Ada.Text_IO, Ada.Text_IO.Text_Streams; ]


   Buffer : String (1..100_000);
begin
   String'Read (Stream (Standard_Input), Buffer);

You are using C bindings improperly and you need not C bindings in order to
read the standard input.
