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 and PCRE_CONFIG_MATCH_LIMIT_RECURSION, when it must
43: point to an unsigned long integer. The available codes are:
44: <pre>
45: PCRE_CONFIG_JIT Availability of just-in-time compiler
46: support (1=yes 0=no)
1.1.1.2 misho 47: PCRE_CONFIG_JITTARGET String containing information about the
48: target architecture for the JIT compiler,
49: or NULL if there is no JIT support
1.1 misho 50: PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4
1.1.1.4 ! misho 51: PCRE_CONFIG_PARENS_LIMIT Parentheses nesting limit
1.1 misho 52: PCRE_CONFIG_MATCH_LIMIT Internal resource limit
53: PCRE_CONFIG_MATCH_LIMIT_RECURSION
54: Internal recursion depth limit
55: PCRE_CONFIG_NEWLINE Value of the default newline sequence:
56: 13 (0x000d) for CR
57: 10 (0x000a) for LF
58: 3338 (0x0d0a) for CRLF

60: -1 for ANY
61: PCRE_CONFIG_BSR Indicates what \R matches by default:
62: 0 all Unicode line endings
63: 1 CR, LF, or CRLF only
64: PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
65: Threshold of return slots, above which
66: <b>malloc()</b> is used by the POSIX API
67: PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap)
1.1.1.2 misho 68: PCRE_CONFIG_UTF16 Availability of UTF-16 support (1=yes
69: 0=no); option for <b>pcre16_config()</b>

1.1.1.2 misho 78: The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. That error
1.1.1.3 misho 79: is also given if PCRE_CONFIG_UTF16 or PCRE_CONFIG_UTF32 is passed to
80: <b>pcre_config()</b>, if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 is passed to
81: <b>pcre16_config()</b>, or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16 is passed to
82: <b>pcre32_config()</b>.
