25DESCRIPTION
26</b><br>
27<P>
28The <i>bytes</i> argument must point to a serialized byte stream that was
29originally created by <b>pcre2_serialize_encode()</b> (though it may have been
30saved on disc or elsewhere in the meantime). The function returns the number of
31serialized patterns in the byte stream, or one of the following negative error
32codes:
33<pre>
34  PCRE2_ERROR_BADMAGIC  mismatch of id bytes in <i>bytes</i>
35  PCRE2_ERROR_BADMODE   mismatch of variable unit size or PCRE version
36  PCRE2_ERROR_NULL      the argument is NULL
37</pre>
38PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
39on a system with different endianness.
