  25. DESCRIPTION

  26. </b><br>
    27. 

  27. <P>
    28. 

  28. This function requests JIT compilation, which, if the just-in-time compiler is
    29. 

  29. available, further processes a compiled pattern into machine code that executes
    30. 

  30. much faster than the <b>pcre2_match()</b> interpretive matching function. Full
    31. 

  31. details are given in the
    32. 

  32. <a href="pcre2jit.html"><b>pcre2jit</b></a>
    33. 

  33. documentation.
    34. 

  34. </P>
    35. 

  35. <P>
    36. 

  36. The first argument is a pointer that was returned by a successful call to
    37. 

  37. <b>pcre2_compile()</b>, and the second must contain one or more of the following
    38. 

  38. bits:
    39. 

  39. <pre>
    40. 

  40.   PCRE2_JIT_COMPLETE      compile code for full matching
    41. 

  41.   PCRE2_JIT_PARTIAL_SOFT  compile code for soft partial matching
    42. 

  42.   PCRE2_JIT_PARTIAL_HARD  compile code for hard partial matching
    43. 

  43. </pre>
    44. 

  44. There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been
    45. 

  45. superseded by the <b>pcre2_compile()</b> option PCRE2_MATCH_INVALID_UTF. The old
    46. 

  46. option is deprecated and may be removed in the future.
    47. 

  47. </P>
    48. 

  48. <P>
    49. 

  49. The yield of the function is 0 for success, or a negative error code otherwise.
    50. 

  50. In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or
    51. 

  51. if an unknown bit is set in <i>options</i>. The function can also return
    52. 

  52. PCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for the
    53. 

  53. compiler, even if it was because of a system security restriction.
