Sure looks like you're trying to write on a non-open file (stream=0
suggests you're passing a NULL file pointer to fprintf).
As for your later message, no you can't return an SQL NULL by
returning a NULL pointer. The only way to return NULLs cleanly
is to use the v1 function call interface, within which the macro
PG_RETURN_NULL() works. See the documentation about writing C
functions.
