 The parsed CMS_ContentInfo structure is returned or NULL if an
 error occurred.
 
+SMIME_read_CMS_ex() is similar to SMIME_read_CMS() but optionally a previously
+created I<cms> CMS_ContentInfo object can be supplied as well as some I<flags>.
+To create a I<cms> object use L<CMS_ContentInfo_new_ex(3)>.
+If the I<flags> argument contains B<CMS_BINARY> then the input is assumed to be
+in binary format and is not translated to canonical form.
+If in addition B<SMIME_ASCIICRLF> is set then the binary input is assumed
+to be followed by B<CR> and B<LF> characters, else only by an B<LF> character.
+If I<flags> is 0 and I<cms> is NULL then it is identical to SMIME_read_CMS().
