NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include 

       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 inter-
       nal 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_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 compiled with UTF-8 support in order  to  use
       PCRE_UTF8 (or 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 API in the
       pcreapi page.
