+.SH DESCRIPTION
+.rs
+.sp
+This function matches a compiled regular expression against a given subject
+string, using an alternative matching algorithm that scans the subject string
+just once (except when processing lookaround assertions). This function is
+\fInot\fP Perl-compatible (the Perl-compatible matching function is
+\fBpcre2_match()\fP). The arguments for this function 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
+ \fIworkspace\fP Points to a vector of ints used as working space
+ \fIwscount\fP Number of elements in the vector
+.sp
+For \fBpcre2_dfa_match()\fP, a match context is needed only if you want to set
+up a callout function or specify the heap limit or the match or the recursion
+depth limits. The \fIlength\fP and \fIstartoffset\fP values are code units, not
+characters. 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 is not the beginning of a line
+ PCRE2_NOTEOL Subject 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
+.\" 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
+ PCRE2_DFA_RESTART Restart after a partial match
+ PCRE2_DFA_SHORTEST Return only the shortest match
+.sp
+There are restrictions on what may appear in a pattern when using this matching
+function. Details are given in the
+.\" HREF
+\fBpcre2matching\fP
+.\"
+documentation. For details of partial matching, see the
+.\" HREF
+\fBpcre2partial\fP

+page. There is a complete description of the PCRE2 native API in the
+.\" HREF
+\fBpcre2api\fP

+page and a description of the POSIX API in the
+.\" HREF
+\fBpcre2posix\fP
