SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>int32_t pcre2_serialize_get_number_of_codes(const uint8_t *<i>bytes</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
The <i>bytes</i> argument must point to a serialized byte stream that was
originally created by <b>pcre2_serialize_encode()</b> (though it may have been
saved on disc or elsewhere in the meantime). The function returns the number of
serialized patterns in the byte stream, or one of the following negative error
codes:
<pre>
  PCRE2_ERROR_BADMAGIC  mismatch of id bytes in <i>bytes</i>
  PCRE2_ERROR_BADMODE   mismatch of variable unit size or PCRE version
  PCRE2_ERROR_NULL      the argument is NULL
</pre>
PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
on a system with different endianness.
</P>
