ILE ISF and freopen

[Walt Fles <wfles@xxxxxxxxxxx>]

Hello All,
Ive read the archived articles but I still can't seem to get this to work:

I have a simple example, that I compile using CRTBNDC, with the option 
SYSIFCOPT(*IFSIO):

int
main( int argc, char ** argv ) {
   FILE *cso;
   FILE *cse;

   char *captured = "./captured";

   cso = freopen( captured,"w", stdout );

   cse = freopen( captured, "a", stderr );

   fprintf( stdout, "This should not go to stdout but to a file!\n" );
   fprintf( stderr, "This should not go to stderr but to a file!\n" );

   fclose( cso );
   fclose( cse );

   exit(0);
}

After compiling and running it with:
call pgm(lib/thisprogram)

I get a terminal window, with the messages displayed.
If I go into qsh and set the variable QIBM_USE_DESCRIPTOR_STDIO="Y"
and execute the program ( /qsys.lib/mylib.lib/thisprogram.pgm )

If I compile and run this program under UNIX it works as youd think it 
would.

Any ideas? Im running OS400 V5R2.
Maybe this was addressed in a PTF? Im stumped here!

Thanks!
