efun: regexp_package

SYNOPSIS:

        #include <regexp.h>

        int regexp_package()

DESCRIPTION:

        Return which regexp package is used by default:

          RE_TRADITIONAL: traditional regexps
          RE_PCRE:        PCRE

        As the package can be selected at runtime through the
        REGEXP_PACKAGE driver hook, there is no good way to determine
        the package at LPC compile time.
        Match the pattern <pattern> (interpreted according to <opt> if
        given) against all strings in list, and return a new array with all
        strings that matched.

        If there is an error in the regular expression, a runtime
        error will be raised.

EXAMPLE:

        string strs;
        string pattern;
        
        if (regexp_package() == RE_PCRE)
            pattern = "\\<help\\>.*\\<me\\>";
        else
            pattern = "\\bhelp\\b.*\\bme\\b";

        if (strs = regexp( ({"please, help me Sir John."}),
                         , pattern
                         ))
        {
           if (sizeof(strs)
              write("It matches.\n");
        }

        The regular expression will test the given string (which is
        packed into an array) if there is something like "help ... me"
        inside of it.
