NAME        top

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS        top

#include <pcre2.h>int32_t pcre2_serialize_get_number_of_codes(const uint8_t *bytes);

DESCRIPTION        top

       Thebytes argument must point to a serialized byte stream that was       originally created bypcre2_serialize_encode()(though it may have       been saved on disc or elsewhere in the meantime). The function       returns the number of serialized patterns in the byte stream, or       one of the following negative error codes:         PCRE2_ERROR_BADMAGIC  mismatch of id bytes inbytes         PCRE2_ERROR_BADMODE   mismatch of variable unit size or PCRE       version         PCRE2_ERROR_NULL      the argument is NULL       PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it       was compiled on a system with different endianness.       There is a complete description of the PCRE2 native API in thepcre2apipage and a description of the serialization functions in       thepcre2serializepage.
