Why are my attempts to open a file using open for writing failing?

When I attempt to open a file to write, I get an error: Ada.IO_Exceptions.Name_Error. The procedure call is Ada.Text_IO.Open; the file name is C:\CC_TEST_LOG.TXT. This file does not exist.

This is on开发者_JAVA技巧 Windows XP on an NTFS partition. The user has permissions to create and write to the directory. The filename is well under the WIN32 max path length.

 name_2 : String := "C:\CC_TEST_LOG.TXT"
 if name_2'last > name_2'first then
    begin
       Ada.Text_IO.Open(file, Ada.Text_IO.Out_File, name_2);
       Ada.Text_IO.Put_Line(
          "CC_Test_Utils: LogFile: ERROR: Open, File "
          & name_2);
       return;
    exception
       when The_Error : others =>
          Ada.Text_IO.Put_Line(
             "CC_Test_Utils: LogFile: ERROR: Open Failed; "
              & Ada.Exceptions.Exception_Name(The_Error)
              & ", File " & name_2);
    end;
 end if;

If the "file does not exist," you should Create it first, for example. Note that "For text input-output, the procedures Create, Open, and Reset have additional effects described in subclause A.10.2."
