PCRE2_SER...R_OF_CODES(3)  Library Functions Manual  PCRE2_SER...R_OF_CODES(3)

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 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.
