74 Before compiled patterns can be saved they must be serialized, which in PCRE2
76 contain any number of compiled patterns, but they must all use the same
86 from a list of compiled patterns. Its first two arguments specify the list,
87 being a pointer to a vector of pointers to compiled patterns, and the length of
93 of serialized patterns, or one of the following negative error codes:
95   PCRE2_ERROR_BADDATA      the number of patterns is zero or less
96   PCRE2_ERROR_BADMAGIC     mismatch of id bytes in one of the patterns
98   PCRE2_ERROR_MIXEDTABLES  the patterns do not all use the same tables
105 Once a set of patterns has been serialized you can save the data in any
106 appropriate manner. Here is sample code that compiles two patterns and writes
