uncompress a CMS CompressedData structure
CMS_uncompress(CMS_ContentInfo *cms, BIO *dcont, BIO *out, unsigned int flags);
CMS_uncompress() extracts and uncompresses the content of a CMS CompressedData structure cms and writes it to out. In the rare case where the compressed content is detached, pass it in via dcont. For normal use, set dcont to
NULL. The only currently supported compression algorithm is zlib: if the structure indicates the use of any other algorithm, an error is returned. If zlib support is not compiled in,
CMS_uncompress() always returns an error. If the
CMS_TEXTbit is set in flags, MIME headers for type text/plain are deleted from the content. If the content is not of type text/plain, an error is returned.
CMS_uncompress() returns 1 for success or 0 for failure. The error can be obtained from ERR_get_error(3). CMS_compress(3), CMS_ContentInfo_new(3)
