  31. DESCRIPTION
  32. </b><br>
  33. <P>
  34. This function makes it possible for a client program to find out which optional
  35. features are available in the version of the PCRE library it is using. The
  36. arguments are as follows:
  37. <pre>
  38. <i>what</i> A code specifying what information is required
  39. <i>where</i> Points to where to put the data
  40. </pre>
  41. The <i>where</i> argument must point to an integer variable, except for
  42. PCRE_CONFIG_MATCH_LIMIT, PCRE_CONFIG_MATCH_LIMIT_RECURSION, and
  43. PCRE_CONFIG_PARENS_LIMIT, when it must point to an unsigned long integer,
  44. and for PCRE_CONFIG_JITTARGET, when it must point to a const char*.
  45. The available codes are:
  46. <pre>
  47. PCRE_CONFIG_JIT Availability of just-in-time compiler
  48. support (1=yes 0=no)
  49. PCRE_CONFIG_JITTARGET String containing information about the
  50. target architecture for the JIT compiler,
  51. or NULL if there is no JIT support
  52. PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4
  53. PCRE_CONFIG_PARENS_LIMIT Parentheses nesting limit
  54. PCRE_CONFIG_MATCH_LIMIT Internal resource limit
  55. PCRE_CONFIG_MATCH_LIMIT_RECURSION
  56. Internal recursion depth limit
  57. PCRE_CONFIG_NEWLINE Value of the default newline sequence:
  58. 13 (0x000d) for CR
  59. 10 (0x000a) for LF
  60. 3338 (0x0d0a) for CRLF
  61. -2 for ANYCRLF
  62. -1 for ANY
  63. PCRE_CONFIG_BSR Indicates what \R matches by default:
  64. 0 all Unicode line endings
  65. 1 CR, LF, or CRLF only
  66. PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
  67. Threshold of return slots, above which
  68. <b>malloc()</b> is used by the POSIX API
  69. PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap)
  70. PCRE_CONFIG_UTF16 Availability of UTF-16 support (1=yes
  71. 0=no); option for <b>pcre16_config()</b>
  72. PCRE_CONFIG_UTF32 Availability of UTF-32 support (1=yes
  73. 0=no); option for <b>pcre32_config()</b>
  74. PCRE_CONFIG_UTF8 Availability of UTF-8 support (1=yes 0=no);
  75. option for <b>pcre_config()</b>
  76. PCRE_CONFIG_UNICODE_PROPERTIES
  77. Availability of Unicode property support
  78. (1=yes 0=no)
  79. </pre>
  80. The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. That error
  81. is also given if PCRE_CONFIG_UTF16 or PCRE_CONFIG_UTF32 is passed to
  82. <b>pcre_config()</b>, if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 is passed to
  83. <b>pcre16_config()</b>, or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16 is passed to
  84. <b>pcre32_config()</b>.
