The problem is, there is a nameclash between C stdin/stdout/stderr, declared somewhere in c.stdio I guess, and mine. When you took those out, you were actually calling global scanf(), which does not support D strings (stream.d has a rewritten version of it). So, either you provide the fully qualified name, like this:

	stream.stdin.scanf(".*s", &name);

Or declare an alias:

	File cin, cout, cerr;
	static this()
	{
		cin = stream.stdin;
		cout = stream.stdout;
		cerr = stream.stderr;
	}

You could also add the above into stream.d itself (I will probably do it myself for the next version). Or just don't import c.stdlib and c.stdio...

By the way, what should be the new name for standard streams? Since std* is
already taken by C ones, should I use cin/cout/cerr? Or something else?
I will appreciate any ideas...

Can't use sin/sout because sin is a math function.

Probably fin/fout would be bad because fin can mean "end" in some languages. ;)

how about input/output/error?

"input" sounds like a name of the action, not an object... besides, there's
already class Error, and I'd like to avoid such small differences.

progress made but still experiencing problems.
I decided not to import c.stdlib and c.stdio but when I compile the program
I get the following error messages:

untitled.obj(untitled)
 Error 42: Symbol Undefined _Dstream_stdout_C4File
untitled.obj(untitled)
 Error 42: Symbol Undefined _Dstream_stdin_C4File
--- errorlevel 2

note: prior to compiling I went to your (Pavel) website and downloaded stream.d to replace the one in the src directory. Don't know if that makes a difference.

good points... My final suggestion would be to use din/dout/derr. Otherwise id say to go with cin/cout/cerr. Besides, not to many people will have a problem using cin/cout/cerr because they are already familiar with it.

The problem is simple: you still _link_ with the old version of stream.d, because it is inside phobos.lib, which is linked first. You need to patch your phobos.lib to replace old stream.obj inside it with the new one. Just copy stream.obj to D's LIB directory, then go there and type:

	lib phobos.lib -+stream.obj;

Whew... =)

Thanks! Problem eliminated.

----------------------------------------
Next stage in development:
----------------------------------------

what is the D "stream" equivalent of establishing an output or input stream
and binding it to a file?
C++ e.g.:

ifstream inData;
ofstram outData;

int main() {
    ...
    inData.open ("input.dat");
    ...
    inData.close
    outData.open ("output.dat")
    ...
    outData.close
    ...
    return 0;
}

Thanks
Andrew

I did what you said (lib phobos.lib -+ stream.obj), but when I try this:

import file;
import stream;
import c.stdio;

void main()
{
    File input=new File(GetStdHandle(-10), FileMode.In);

    char [30] W;

    scanf("%s",(char*)W);
    printf("%s\n",(char*)W);

    char [] w;

    input.scanf("%.*s",w);
    printf("%.*s\n",w);
}

I get this:

windows.d(14067): function GetStdHandle symbol windows.GetStdHandle
conflicts wi
th stream.GetStdHandle at stream.d(1125)

Now what?
