The VALUE section in the help for 'unlink' says:
| 0| for success, |1| for failure. Not deleting a non-existent file is
not a failure, nor is being unable to delete a directory if |recursive =
FALSE|. However, missing values in |x| result are regarded as failures.
The last phrase doesn't make sense to me. Should it be either "missing
values in x are regarded as failures" or "missing values in x result in
failure" ?
Also, after reading the docs, I'm still unable to work out if unlink()
will return 1 when the user tries to recursively delete a directory on
systems that don't support recursive=T.
The DETAILS section says "recursive=TRUE is not supported on all
platforms, and may be ignored, with a warning", which could be
interpreted as implying no special action when recursive=TRUE is not
implemented (other than a warning()), and the VALUE section doesn't say
what the return value will be under such conditions.
I've skimmed the various *_unlink functions in src/main/platform.c, and
it looks like they all implement recursive=TRUE, so I'm still in the
dark about the required behavior on systems that don't support it.
Could this be clarified in the help file?
thanks,
Tony Plate
