   40 DESCRIPTION
   41 </b><br>
   42 <P>
   43 This function compiles a regular expression into an internal form. It is the
   44 same 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>
   56 The 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>
   98 PCRE must be built with UTF support in order to use PCRE_UTF8/16/32 and
   99 PCRE_NO_UTF8/16/32_CHECK, and with UCP support if PCRE_UCP is used.

  102 The yield of the function is a pointer to a private data structure that
  103 contains the compiled pattern, or NULL if an error was detected. Note that
  104 compiling regular expressions with one version of PCRE for use with a different
  105 version is not guaranteed to work and may cause crashes.
