SYNOPSIS

#include <pcre2.h>

int32_t pcre2_serialize_encode(pcre2_code **codes, int32_t number_of_codes, uint32_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:

  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 serialized 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 corrupted, or that a slot in the vector does not point to a compiled pattern.
