+DESCRIPTION
+</b><br>
+<P>
+This function studies a compiled pattern, to see if additional information can
+be extracted that might speed up matching. Its arguments are:
+<pre>
+ <i>code</i> A compiled regular expression
+ <i>options</i> Options for <b>pcre[16|32]_study()</b>
+ <i>errptr</i> Where to put an error message
+</pre>
+If the function succeeds, it returns a value that can be passed to
+<b>pcre[16|32]_exec()</b> or <b>pcre[16|32]_dfa_exec()</b> via their <i>extra</i>
+arguments.
+</P>
+<P>
+If the function returns NULL, either it could not find any additional
+information, or there was an error. You can tell the difference by looking at
+the error value. It is NULL in first case.
+</P>
+<P>
+The only option is PCRE_STUDY_JIT_COMPILE. It requests just-in-time compilation
+if possible. If PCRE has been compiled without JIT support, this option is
+ignored. See the
+<a href="pcrejit.html"><b>pcrejit</b></a>
+page for further details.
