+DESCRIPTION

+<P>
+This function matches a compiled regular expression against a given subject
+string, and returns offsets to capturing subexpressions. Its arguments are:
+</P>
+<P>
+<pre>
+ <i>code</i> Points to the compiled pattern
+ <i>extra</i> Points to an associated <b>pcre_extra</b> structure,
+ or is NULL
+ <i>subject</i> Points to the subject string
+ <i>length</i> Length of the subject string, in bytes
+ <i>startoffset</i> Offset in bytes in the subject at which to
+ start matching
+ <i>options</i> Option bits
+ <i>ovector</i> Points to a vector of ints for result offsets
+ <i>ovecsize</i> Size of the vector (a multiple of 3)
+</PRE>
+</P>
+<P>
+The options are:
+</P>
+<P>
+<pre>
+ PCRE_ANCHORED Match only at the first position
+ PCRE_NOTBOL Subject is not the beginning of a line
+ PCRE_NOTEOL Subject is not the end of a line
+ PCRE_NOTEMPTY An empty string is not a valid match
+ PCRE_NO_UTF8_CHECK Do not check the subject for UTF-8
+ validity (only relevant if PCRE_UTF8
+ was set at compile time)
+</PRE>
