29 This function studies a compiled pattern, to see if additional information can
30 be extracted that might speed up matching. Its arguments are:
31 <pre>
32 <i>code</i> A compiled regular expression
33 <i>options</i> Options for <b>pcre_study()</b>
34 <i>errptr</i> Where to put an error message
35 </pre>
36 If the function succeeds, it returns a value that can be passed to
37 <b>pcre_exec()</b> or <b>pcre_dfa_exec()</b> via their <i>extra</i> arguments.
38 </P>
39 <P>
40 If the function returns NULL, either it could not find any additional
41 information, or there was an error. You can tell the difference by looking at
42 the error value. It is NULL in first case.
43 </P>
44 <P>
45 The only option is PCRE_STUDY_JIT_COMPILE. It requests just-in-time compilation
46 if possible. If PCRE has been compiled without JIT support, this option is
47 ignored. See the
48 <a href="pcrejit.html"><b>pcrejit</b></a>
49 page for further details.

52 There is a complete description of the PCRE native API in the
