NAME

       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       int32_t pcre2_serialize_get_number_of_codes(const uint8_t *bytes);

DESCRIPTION

       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 following 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 POSIX API in the pcre2posix page.
