PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       int32_t pcre2_serialize_get_number_of_codes(const uint8_t *bytes);


       The  bytes  argument  must  point  to a serialized byte stream that was
       originally created by pcre2_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 follow-
       ing negative error codes:

         PCRE2_ERROR_BADMAGIC  mismatch of id bytes in bytes
         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 the pcre2api
       page and a description of the serialization functions in the pcre2seri-
       alize page.
