.sp
This function matches a compiled regular expression against a given subject
string, using a matching algorithm that is similar to Perl's. It returns
offsets to captured substrings. Its arguments are:
offsets to what it has matched and to captured substrings via the
\fBmatch_data\fP block, which can be processed by functions with names that
start with \fBpcre2_get_ovector_...()\fP or \fBpcre2_substring_...()\fP. The
return from \fBpcre2_match()\fP is one more than the highest numbered capturing
pair that has been set (for example, 1 if there are no captures), zero if the
vector of offsets is too small, or a negative error code for no match and other
errors. The function arguments are:

\fIcode\fP Points to the compiled pattern
\fIsubject\fP Points to the subject string
