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 abstract 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_se- rialize_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_se- rialize_free(). The yield of the function is the number of serialized pat- terns, 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. There is a complete description of the PCRE2 native API in the pcre2api page and a description of the serialization functions in the pcre2serialize page.
