Hi,

Im trying to write a CGI lib in D, and it requires stdin be put in 
binaru mode for windows, which is done with setmode(), declared in io.h 
and is in snn.lib.  Here is the code:

import std.c.stdio;

void main ()
{

   version ( Windows )
     {
       int O_BINARY = 0x8000;
       extern ( C ) int setmode(int,int);
       setmode(stdin._file ,O_BINARY);
     }

}

And the error:

stest.obj(stest)
  Error 42: Symbol Undefined __D5stest4mainFZv7setmodeMUiiZi
--- errorlevel 1

Im explictly linking to snn.lib ( is that needed ? ) , why is it still 
undefined ?

Thanks,
Charlie

Move the 'extern(C)' declaration out of the main() function.

 import std.c.stdio;
 version ( Windows ) extern ( C ) int setmode(int,int);

 void main ()
 {
   version ( Windows )
     {
       int O_BINARY = 0x8000;
       setmode(stdin._file ,O_BINARY);
     }
 }
