A.12.2 The Package Text_IO.Text_Streams
The package Text_IO.Text_Streams provides a function
for treating a text file as a stream.
Static Semantics
The library package
Text_IO.Text_Streams has the following declaration:
{
AI12-0302-1}
with Ada.Streams;
package Ada.Text_IO.Text_Streams
with Global =>
in out synchronized is
type Stream_Access
is access all Streams.Root_Stream_Type'Class;
function Stream (File :
in File_Type)
return Stream_Access;
end Ada.Text_IO.Text_Streams;
The Stream function has the same effect as the corresponding
function in Streams.Stream_IO.
NOTE 1 The ability to obtain a stream
for a text file allows Current_Input, Current_Output, and Current_Error
to be processed with the functionality of streams, including the mixing
of text and binary input-output, and the mixing of binary input-output
for different types.
NOTE 2 Performing operations on the
stream associated with a text file does not affect the column, line,
or page counts.
