NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       pcre *pcre_compile(const char *pattern, int options,
            const char **errptr, int *erroffset,
            const unsigned char *tableptr);

DESCRIPTION

       This  function  compiles  a regular expression into an internal form. Its arguments
       are:

         pattern       A zero-terminated string containing the
                         regular expression to be compiled
         options       Zero or more option bits
         errptr        Where to put an error message
         erroffset     Offset in pattern where error was found
         tableptr      Pointer to character tables, or NULL to
                         use the built-in default

       The option bits are:

         PCRE_ANCHORED         Force pattern anchoring
         PCRE_AUTO_CALLOUT     Compile automatic callouts
         PCRE_CASELESS         Do caseless matching
         PCRE_DOLLAR_ENDONLY   $ not to match newline at end
         PCRE_DOTALL           . matches anything including NL
         PCRE_EXTENDED         Ignore whitespace and # comments
         PCRE_EXTRA            PCRE extra features
                                 (not much use currently)
         PCRE_MULTILINE        ^ and $ match newlines within data
         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)

       PCRE  must  be  built  with  UTF-8  support  in  order   to   use   PCRE_UTF8   and
       PCRE_NO_UTF8_CHECK.

       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.

       There is a complete description of the PCRE native API in the pcreapi  page  and  a
       description of the POSIX API in the pcreposix page.
