353=head2 Functions in the C<urxvt> Package
354
355=over 4
356
357=item $term = new urxvt [arg...]
358
359Creates a new terminal, very similar as if you had started it with
360C<system $binfile, arg...>. Croaks (and probably outputs an error message)
361if the new instance couldn't be created. Returns C<undef> if the new
362instance didn't initialise perl, and the terminal object otherwise. The
363C<init> and C<start> hooks will be called during the call.
364
365=item urxvt::fatal $errormessage
366
367Fatally aborts execution with the given error message. Avoid at all
368costs! The only time this is acceptable is when the terminal process
369starts up.
370
371=item urxvt::warn $string
372
373Calls C<rxvt_warn> with the given string which should not include a
374newline. The module also overwrites the C<warn> builtin with a function
375that calls this function.
376
377Using this function has the advantage that its output ends up in the
378correct place, e.g. on stderr of the connecting urxvtc client.
379
380=item $is_safe = urxvt::safe
381
382Returns true when it is safe to do potentially unsafe things, such as
383evaluating perl code specified by the user. This is true when urxvt was
384started setuid or setgid.
385
386=item $time = urxvt::NOW
387
388Returns the "current time" (as per the event loop).

400=head2 RENDITION
401
402Rendition bitsets contain information about colour, font, font styles and
403similar information for each screen cell.
404
405The following "macros" deal with changes in rendition sets. You should
406never just create a bitset, you should always modify an existing one,
407as they contain important information required for correct operation of
408rxvt-unicode.
409
410=over 4
411
412=item $rend = urxvt::DEFAULT_RSTYLE
413
414Returns the default rendition, as used when the terminal is starting up or
415being reset. Useful as a base to start when creating renditions.
416
417=item $rend = urxvt::OVERLAY_RSTYLE
418
419Return the rendition mask used for overlays by default.
420
421=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
422
423Return the bit that enabled bold, italic, blink, reverse-video and
424underline, respectively. To enable such a style, just logically OR it into
425the bitset.
426
427=item $foreground = urxvt::GET_BASEFG $rend
428
429=item $background = urxvt::GET_BASEBG $rend
430
431Return the foreground/background colour index, respectively.

434
435=item $rend = urxvt::SET_BGCOLOR ($rend, $new_colour)
436
437Replace the foreground/background colour in the rendition mask with the
438specified one.
439
440=item $value = urxvt::GET_CUSTOM ($rend)
441
442Return the "custom" value: Every rendition has 5 bits for use by
443extensions. They can be set and changed as you like and are initially
444zero.
445
446=item $rend = urxvt::SET_CUSTOM ($rend, $new_value)
