                     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>

                     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
