23 This function studies a compiled pattern, to see if additional information can
24 be extracted that might speed up matching. Its arguments are:
25 </P>
26 <P>
27 <pre>
28 <i>code</i> A compiled regular expression
29 <i>options</i> Options for <b>pcre_study()</b>
30 <i>errptr</i> Where to put an error message
31 </PRE>
32 </P>
33 <P>
34 If the function returns NULL, either it could not find any additional
35 information, or there was an error. You can tell the difference by looking at
36 the error value. It is NULL in first case.
37 </P>
38 <P>
39 There are currently no options defined; the value of the second argument should
40 always be zero.

43 There is a complete description of the PCRE API in the
44 <a href="pcreapi.html"><b>pcreapi</b></a>
