It is the 31 same as <b>pcre_compile2()</b>, except for the absence of the <i>errorcodeptr</i> 32 argument. Its arguments are: 33 <pre> 34 <i>pattern</i> A zero-terminated string containing the 35 regular expression to be compiled 36 <i>options</i> Zero or more option bits 37 <i>errptr</i> Where to put an error message 38 <i>erroffset</i> Offset in pattern where error was found 39 <i>tableptr</i> Pointer to character tables, or NULL to 40 use the built-in default 41 </pre> 42 The option bits are: 43 <pre> 44 PCRE_ANCHORED Force pattern anchoring 45 PCRE_AUTO_CALLOUT Compile automatic callouts 46 PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF 47 PCRE_BSR_UNICODE \R matches all Unicode line endings 48 PCRE_CASELESS Do caseless matching 49 PCRE_DOLLAR_ENDONLY $ not to match newline at end 50 PCRE_DOTALL . matches anything including NL 51 PCRE_DUPNAMES Allow duplicate names for subpatterns 52 PCRE_EXTENDED Ignore whitespace and # comments 53 PCRE_EXTRA PCRE extra features 54 (not much use currently) 55 PCRE_FIRSTLINE Force matching to be before newline 56 PCRE_JAVASCRIPT_COMPAT JavaScript compatibility 57 PCRE_MULTILINE ^ and $ match newlines within data 58 PCRE_NEWLINE_ANY Recognize any Unicode newline sequence 59 PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline 60 sequences 61 PCRE_NEWLINE_CR Set CR as the newline sequence 62 PCRE_NEWLINE_CRLF Set CRLF as the newline sequence 63 PCRE_NEWLINE_LF Set LF as the newline sequence 64 PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren- 65 theses (named ones available) 66 PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8 67 validity (only relevant if 68 PCRE_UTF8 is set) 69 PCRE_UCP Use Unicode properties for \d, \w, etc. 70 PCRE_UNGREEDY Invert greediness of quantifiers 71 PCRE_UTF8 Run in UTF-8 mode 72 </pre> 73 PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and 74 PCRE_NO_UTF8_CHECK, and with UCP support if PCRE_UCP is used. 75 </P> 76 <P> 77 The yield of the function is a pointer to a private data structure that 78 contains the compiled pattern, or NULL if an error was detected. Note that 79 compiling regular expressions with one version of PCRE for use with a different 80 version is not guaranteed to work and may cause crashes. 81 </P> 82 <P> 83 There is a complete description of the PCRE native API in the 84 <a href="pcreapi.html"><b>pcreapi</b></a> 85 page and a description of the POSIX API in the 86 <a href="pcreposix.html"><b>pcreposix</b></a> 87 page. 88 <p> 89 Return to the <a href="index.html">PCRE index page</a>. 90 </p> 91
