RE: c++ query

[Syed Khaleelulla <Syed.Khaleelulla@xxxxxxxxx>]

  Try to open the file after creating it.

The code which worked for me is here,
--------------
main()
{

  int fd;
  char filename[10];
  char text[]="Hello";

  scanf("%s", filename);

  close( 1 );

  creat ( filename, 0x666 );

  open( filename, O_WRONLY );

  printf("the printf is printing %s", text );

}
---------------------
-Thanks,
Syed Khaleelulla.
