PCRE2_SERIALIZE_ENCODE(3)PCRE2_SERIALIZE_ENCODE(3)NAME
PCRE2 - Perl-compatible regular expressions (revised API)
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 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 POSIX API in the pcre2posix page.
