+.SH DESCRIPTION
+.rs
+.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 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:
+.sp
+ \fIcode\fP Points to the compiled pattern
+ \fIsubject\fP Points to the subject string
+ \fIlength\fP Length of the subject string
+ \fIstartoffset\fP Offset in the subject at which to start matching
+ \fIoptions\fP Option bits
+ \fImatch_data\fP Points to a match data block, for results
+ \fImcontext\fP Points to a match context, or is NULL
+.sp
+A match context is needed only if you want to:
+.sp
+ Set up a callout function
+ Set a matching offset limit
+ Change the heap memory limit
+ Change the backtracking match limit
+ Change the backtracking depth limit
+ Set custom memory management specifically for the match
+.sp
+The \fIlength\fP and \fIstartoffset\fP values are code
+units, not characters. The length may be given as PCRE2_ZERO_TERMINATE for a
+subject that is terminated by a binary zero code unit. The options are:
+.sp
+ PCRE2_ANCHORED Match only at the first position
+ PCRE2_ENDANCHORED Pattern can match only at end of subject
+ PCRE2_NOTBOL Subject string is not the beginning of a line
+ PCRE2_NOTEOL Subject string is not the end of a line
+ PCRE2_NOTEMPTY An empty string is not a valid match
+.\" JOIN
+ PCRE2_NOTEMPTY_ATSTART An empty string at the start of the subject
+ is not a valid match
+ PCRE2_NO_JIT Do not use JIT matching
+.\" JOIN
+ PCRE2_NO_UTF_CHECK Do not check the subject for UTF
+ validity (only relevant if PCRE2_UTF
+ was set at compile time)
+.\" JOIN
+ PCRE2_PARTIAL_HARD Return PCRE2_ERROR_PARTIAL for a partial
+ match even if there is a full match
+.\" JOIN
+ PCRE2_PARTIAL_SOFT Return PCRE2_ERROR_PARTIAL for a partial
+ match if no full matches are found
+.sp
