<b>int32_t pcre2_serialize_encode(pcre2_code **<i>codes</i>,</b>

DESCRIPTION
</b><br>
<P>
This function encodes a list of compiled patterns into a byte stream that can
be saved on disc or elsewhere. Its arguments are:
<pre>
  <i>codes</i>             pointer to a vector containing the list
  <i>number_of_codes</i>   number of slots in the vector
  <i>serialized_bytes</i>  set to point to the serialized byte stream
  <i>serialized_size</i>   set to the number of bytes in the byte stream
  <i>gcontext</i>          pointer to a general context or NULL
</pre>
The context argument is used to obtain memory for the byte stream. When the
serialized data is no longer needed, it must be freed by calling
<b>pcre2_serialize_free()</b>. The yield of the function is the number of
serialized patterns, or one of the following negative error codes:
<pre>
  PCRE2_ERROR_BADDATA      <i>number_of_codes</i> is zero or less
  PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
  PCRE2_ERROR_MEMORY       memory allocation failed
  PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
  PCRE2_ERROR_NULL         an argument other than <i>gcontext</i> is NULL
</pre>
PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
that a slot in the vector does not point to a compiled pattern.
