SYNOPSIS
 

#include &#60;pcre2.h&#62;


int32_t pcre2_serialize_encode(const pcre2_code **codes,
 int32_t number_of_codes, uint8_t **serialized_bytes,
 PCRE2_SIZE *serialized_size, pcre2_general_context *gcontext);

 
DESCRIPTION
 

This function encodes a list of compiled patterns into a byte stream that can
be saved on disc or elsewhere. Its arguments are:
<pre>
 codes pointer to a vector containing the list
 number_of_codes number of slots in the vector
 serialized_bytes set to point to the serialized byte stream
 serialized_size set to the number of bytes in the byte stream
 gcontext 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
pcre2_serialize_free(). The yield of the function is the number of
serialized patterns, or one of the following negative error codes:
<pre>
 PCRE2_ERROR_BADDATA number_of_codes 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 gcontext 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.
