| DESCRIPTION
 | |
| </b><br>
 | |
| <P>
 | |
| This function compiles a regular expression into an internal form. It is the
 | |
| same as <b>pcre_compile2()</b>, except for the absence of the <i>errorcodeptr</i>
 | |
| argument. Its arguments are:
 | |
| <pre>
 | |
|   <i>pattern</i>       A zero-terminated string containing the
 | |
|                   regular expression to be compiled
 | |
|   <i>options</i>       Zero or more option bits
 | |
|   <i>errptr</i>        Where to put an error message
 | |
|   <i>erroffset</i>     Offset in pattern where error was found
 | |
|   <i>tableptr</i>      Pointer to character tables, or NULL to
 | |
|                   use the built-in default
 | |
| </pre>
 | |
| The option bits are:
 | |
| <pre>
 | |
|   PCRE_ANCHORED           Force pattern anchoring
 | |
|   PCRE_AUTO_CALLOUT       Compile automatic callouts
 | |
|   PCRE_BSR_ANYCRLF        \R matches only CR, LF, or CRLF
 | |
|   PCRE_BSR_UNICODE        \R matches all Unicode line endings
 | |
|   PCRE_CASELESS           Do caseless matching
 | |
|   PCRE_DOLLAR_ENDONLY     $ not to match newline at end
 | |
|   PCRE_DOTALL             . matches anything including NL
 | |
|   PCRE_DUPNAMES           Allow duplicate names for subpatterns
 | |
|   PCRE_EXTENDED           Ignore whitespace and # comments
 | |
|   PCRE_EXTRA              PCRE extra features
 | |
|                             (not much use currently)
 | |
|   PCRE_FIRSTLINE          Force matching to be before newline
 | |
|   PCRE_JAVASCRIPT_COMPAT  JavaScript compatibility
 | |
|   PCRE_MULTILINE          ^ and $ match newlines within data
 | |
|   PCRE_NEWLINE_ANY        Recognize any Unicode newline sequence
 | |
|   PCRE_NEWLINE_ANYCRLF    Recognize CR, LF, and CRLF as newline
 | |
|                             sequences
 | |
|   PCRE_NEWLINE_CR         Set CR as the newline sequence
 | |
|   PCRE_NEWLINE_CRLF       Set CRLF as the newline sequence
 | |
|   PCRE_NEWLINE_LF         Set LF as the newline sequence
 | |
|   PCRE_NO_AUTO_CAPTURE    Disable numbered capturing paren-
 | |
|                             theses (named ones available)
 | |
|   PCRE_UNGREEDY           Invert greediness of quantifiers
 | |
|   PCRE_UTF8               Run in UTF-8 mode
 | |
|   PCRE_NO_UTF8_CHECK      Do not check the pattern for UTF-8
 | |
|                             validity (only relevant if
 | |
|                             PCRE_UTF8 is set)
 | |
| </pre>
 | |
| PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and
 | |
| PCRE_NO_UTF8_CHECK.
 | |
| </P>
 | |
| <P>
 | |
| The yield of the function is a pointer to a private data structure that
 | |
| contains the compiled pattern, or NULL if an error was detected. Note that
 | |
| compiling regular expressions with one version of PCRE for use with a different
 | |
| version is not guaranteed to work and may cause crashes.
