| 28 | DESCRIPTION |
| 29 | </b><br> |
| 30 | <P> |
| 31 | This function compiles a regular expression into an internal form. It is the |
| 32 | same as <b>pcre_compile()</b>, except for the addition of the <i>errorcodeptr</i> |
| 33 | argument. The arguments are: |
| 34 | <pre> |
| 35 | <i>pattern</i> A zero-terminated string containing the |
| 36 | regular expression to be compiled |
| 37 | <i>options</i> Zero or more option bits |
| 38 | <i>errorcodeptr</i> Where to put an error code |
| 39 | <i>errptr</i> Where to put an error message |
| 40 | <i>erroffset</i> Offset in pattern where error was found |
| 41 | <i>tableptr</i> Pointer to character tables, or NULL to |
| 42 | use the built-in default |
| 43 | </pre> |
| 44 | The option bits are: |
| 45 | <pre> |
| 46 | PCRE_ANCHORED Force pattern anchoring |
| 47 | PCRE_AUTO_CALLOUT Compile automatic callouts |
| 48 | PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF |
| 49 | PCRE_BSR_UNICODE \R matches all Unicode line endings |
| 50 | PCRE_CASELESS Do caseless matching |
| 51 | PCRE_DOLLAR_ENDONLY $ not to match newline at end |
| 52 | PCRE_DOTALL . matches anything including NL |
| 53 | PCRE_DUPNAMES Allow duplicate names for subpatterns |
| 54 | PCRE_EXTENDED Ignore whitespace and # comments |
| 55 | PCRE_EXTRA PCRE extra features |
| 56 | (not much use currently) |
| 57 | PCRE_FIRSTLINE Force matching to be before newline |
| 58 | PCRE_JAVASCRIPT_COMPAT JavaScript compatibility |
| 59 | PCRE_MULTILINE ^ and $ match newlines within data |
| 60 | PCRE_NEWLINE_ANY Recognize any Unicode newline sequence |
| 61 | PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline |
| 62 | sequences |
| 63 | PCRE_NEWLINE_CR Set CR as the newline sequence |
| 64 | PCRE_NEWLINE_CRLF Set CRLF as the newline sequence |
| 65 | PCRE_NEWLINE_LF Set LF as the newline sequence |
| 66 | PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren- |
| 67 | theses (named ones available) |
| 68 | PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8 |
| 69 | validity (only relevant if |
| 70 | PCRE_UTF8 is set) |
| 71 | PCRE_UCP Use Unicode properties for \d, \w, etc. |
| 72 | PCRE_UNGREEDY Invert greediness of quantifiers |
| 73 | PCRE_UTF8 Run in UTF-8 mode |
| 74 | </pre> |
| 75 | PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and |
| 76 | PCRE_NO_UTF8_CHECK, and with UCP support if PCRE_UCP is used. |
| 77 | </P> |
| 78 | <P> |
| 79 | The yield of the function is a pointer to a private data structure that |
| 80 | contains the compiled pattern, or NULL if an error was detected. Note that |
| 81 | compiling regular expressions with one version of PCRE for use with a different |
| 82 | version is not guaranteed to work and may cause crashes. |
