You can test that for yourself with:

void __fastcall TForm1::fopenButtonClick(TObject *Sender)
{
   Memo1->Clear();

   int filenr = 0;

   Memo1->Lines->Add ( "FOPEN_MAX: " + IntToStr ( FOPEN_MAX ) );

   while ( ++ filenr <= maxwanted )
      {
       char path [MAXPATH+2];

       sprintf ( path, "fopen.%d.txt", filenr );

       if ( ! fopen ( path, "wb" ) )
         break;

       Memo1->Lines->Add ( path );
      }
}

  Memo1->Clear();

   Memo1->Lines->Add ( "FOPEN_MAX: " + IntToStr ( FOPEN_MAX ) );

   int filenr = 0;

   while ( ++ filenr <= maxwanted )
      {
       char path [MAXPATH+2];

       sprintf ( path, "open.%d.txt", filenr );

       int fd = open( path,  // io.h
	O_CREAT | O_TRUNC | O_RDWR |O_BINARY, S_IREAD | S_IWRITE  );

       if ( fd < 1 )
         break;

       Memo1->Lines->Add ( path );
      }
