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
       serialization functions in the pcre2serialize page.
