CID 975621 (#1 of 1): Copy-paste error (COPY_PASTE_ERROR)
   copy_paste_error: rf in fclose(rf) looks like a copy-paste error.
   Should it say fd instead?

471                        (void)fclose(rf);

--------------- Source analysis:

The suspicion stems from the assymetric reaction on error.
Only the read FILE pointer rf was opened inside the function.
So it gets closed in both error cases: with read FILE *rf and
with write FILE *fd.

          if (ferror(rf)) {
                  ...
                  (void)fclose(rf);
          ...
          if (ferror(fd)) {
                  ...
                  (void)fclose(rf);

--------------- Remedy proposal:

In Coverity classify CID 975621 as "False positive" and set its Action
to "Ignore".
