In reply to dave_59:

Code works if we do not pass any ‘mode’ argument while opening file.

That seems to suggest that $fopen with MCD (Multi-Channel Descriptor) works fine in your tool, but not with a “fd” (Recall V2K added the FD concept with type as the 2nd argument to $fopen).

Maybe there is a +v2k switch needed in your tool? Which tool do you use? Also try few things:

  1. Use $ferror after the $fopen to see the “fd” is returned properly
  2. Use plain $fdisplay and see if that works
  3. Try “w” mode first to see if that works.

File IO has been a pain with some tools, but not this bad I suppose.

Good Luck
