| SYNOPSIS |
| </b><br> |
| <P> |
| <b>#include <pcre2.h></b> |
| </P> |
| <P> |
| <b>int pcre2_jit_compile(pcre2_code *<i>code</i>, uint32_t <i>options</i>);</b> |
| </P> |
| <br><b> |
| DESCRIPTION |
| </b><br> |
| <P> |
| This function requests JIT compilation, which, if the just-in-time compiler is |
| available, further processes a compiled pattern into machine code that executes |
| much faster than the <b>pcre2_match()</b> interpretive matching function. Full |
| details are given in the |
| <a href="pcre2jit.html"><b>pcre2jit</b></a> |
| documentation. |
| </P> |
| <P> |
| The first argument is a pointer that was returned by a successful call to |
| <b>pcre2_compile()</b>, and the second must contain one or more of the following |
| bits: |
| <pre> |
| PCRE2_JIT_COMPLETE compile code for full matching |
| PCRE2_JIT_PARTIAL_SOFT compile code for soft partial matching |
| PCRE2_JIT_PARTIAL_HARD compile code for hard partial matching |
| </pre> |
| There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been |
| superseded by the <b>pcre2_compile()</b> option PCRE2_MATCH_INVALID_UTF. The old |
| option is deprecated and may be removed in the future. |
| </P> |
| <P> |
| The yield of the function is 0 for success, or a negative error code otherwise. |
| In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or |
| if an unknown bit is set in <i>options</i>. The function can also return |
| PCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for the |
| compiler, even if it was because of a system security restriction. |
| </P> |
