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