It is the 44same as <b>pcre[16|32]_compile()</b>, except for the addition of the 45<i>errorcodeptr</i> argument. The arguments are: 46<pre> 47 <i>pattern</i> A zero-terminated string containing the 48 regular expression to be compiled 49 <i>options</i> Zero or more option bits 50 <i>errorcodeptr</i> Where to put an error code 51 <i>errptr</i> Where to put an error message 52 <i>erroffset</i> Offset in pattern where error was found 53 <i>tableptr</i> Pointer to character tables, or NULL to 54 use the built-in default 55</pre> 56The option bits are: 57<pre> 58 PCRE_ANCHORED Force pattern anchoring 59 PCRE_AUTO_CALLOUT Compile automatic callouts 60 PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF 61 PCRE_BSR_UNICODE \R matches all Unicode line endings 62 PCRE_CASELESS Do caseless matching 63 PCRE_DOLLAR_ENDONLY $ not to match newline at end 64 PCRE_DOTALL . matches anything including NL 65 PCRE_DUPNAMES Allow duplicate names for subpatterns 66 PCRE_EXTENDED Ignore white space and # comments 67 PCRE_EXTRA PCRE extra features 68 (not much use currently) 69 PCRE_FIRSTLINE Force matching to be before newline 70 PCRE_JAVASCRIPT_COMPAT JavaScript compatibility 71 PCRE_MULTILINE ^ and $ match newlines within data 72 PCRE_NEVER_UTF Lock out UTF, e.g. via (*UTF) 73 PCRE_NEWLINE_ANY Recognize any Unicode newline sequence 74 PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline 75 sequences 76 PCRE_NEWLINE_CR Set CR as the newline sequence 77 PCRE_NEWLINE_CRLF Set CRLF as the newline sequence 78 PCRE_NEWLINE_LF Set LF as the newline sequence 79 PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren- 80 theses (named ones available) 81 PCRE_NO_AUTO_POSSESS Disable auto-possessification 82 PCRE_NO_START_OPTIMIZE Disable match-time start optimizations 83 PCRE_NO_UTF16_CHECK Do not check the pattern for UTF-16 84 validity (only relevant if 85 PCRE_UTF16 is set) 86 PCRE_NO_UTF32_CHECK Do not check the pattern for UTF-32 87 validity (only relevant if 88 PCRE_UTF32 is set) 89 PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8 90 validity (only relevant if 91 PCRE_UTF8 is set) 92 PCRE_UCP Use Unicode properties for \d, \w, etc. 93 PCRE_UNGREEDY Invert greediness of quantifiers 94 PCRE_UTF16 Run <b>pcre16_compile()</b> in UTF-16 mode 95 PCRE_UTF32 Run <b>pcre32_compile()</b> in UTF-32 mode 96 PCRE_UTF8 Run <b>pcre_compile()</b> in UTF-8 mode 97</pre> 98PCRE must be built with UTF support in order to use PCRE_UTF8/16/32 and 99PCRE_NO_UTF8/16/32_CHECK, and with UCP support if PCRE_UCP is used. 100</P> 101<P> 102The yield of the function is a pointer to a private data structure that 103contains the compiled pattern, or NULL if an error was detected. Note that 104compiling regular expressions with one version of PCRE for use with a different 105version is not guaranteed to work and may cause crashes. 106</P> 107<P> 108There is a complete description of the PCRE native API in the 109<a href="pcreapi.html"><b>pcreapi</b></a> 110page and a description of the POSIX API in the 111<a href="pcreposix.html"><b>pcreposix</b></a> 112page. 113<p> 114Return to the <a href="index.html">PCRE index page</a>. 115</p> 116
