+SYNOPSIS
+
+
+#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 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. +
