Subject: [source] del_aubio_source argument can be null
X-Git-Tag: 0.4.9~38
X-Git-Url: https://git.aubio.org/?a=commitdiff_plain;h=8d4ffeb0efa5d26b790d67d985c720cbd3335f78;p=aubio.git

[source] del_aubio_source argument can be null

Most del_ methods in aubio do not check if their argument is NULL, but
del_aubio_source used to, so we keep it this way to avoid breaking
existing programs.
