Of course, instead of using PCRE2_DFA_RESTART, the same technique of re-running
the entire match can also be used with the DFA matching function. Another
possibility is to work with two buffers. If a partial match at offset <i>n</i>
in the first buffer is followed by "no match" when PCRE2_DFA_RESTART is used on
the second buffer, you can then try a new match starting at offset <i>n+1</i> in
the first buffer.
