DESCRIPTION
</b><br>
<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
</PRE>
