="SEC3" href="#TOC1">PARTIAL MATCHING USING pcre2_dfa_match()</a><br>
<P>
The DFA functions move along the subject string character by character, without
backtracking, searching for all possible matches simultaneously. If the end of
the subject is reached before the end of the pattern, there is the possibility
of a partial match, again provided that at least one character has been
inspected.

<P>
When PCRE2_PARTIAL_SOFT is set, PCRE2_ERROR_PARTIAL is returned only if there
have been no complete matches.
