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


       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.
