B<data> is a BIO to write the content to and +B<flags> is an optional set of flags. + +The B<dcont> parameter is used in the rare case where the compressed content +is detached.

If the content is not of type B<text/plain> then an error is +returned. + +=head1 RETURN VALUES + +CMS_uncompress() returns either 1 for success or 0 for failure.
