PCRE2_SERIALIZE_ENCODE(3)  Library Functions Manual  PCRE2_SERIALIZE_ENCODE(3)

NAME
       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       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. Note that this is  not  an  ab-
       stract  format  like  Java  or .NET. Conversion of the byte stream back
       into usable compiled patterns can only happen on a host that is running
       the  same version of PCRE2, with the same code unit width, and the host
       must also have the same endianness, pointer width and PCRE2_SIZE  type.
       The arguments for pcre2_serialize_encode() are:

         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

       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 se-
       rialized patterns, or one of the following negative error codes:

         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

       PCRE2_ERROR_BADMAGIC means either that a pattern's code has  been  cor-
       rupted,  or that a slot in the vector does not point to a compiled pat-
       tern.

       There is a complete description of the PCRE2 native API in the pcre2api
       page and a description of the serialization functions in the pcre2seri-
       alize page.
