349
350=over 4
351
352=item $term = new urxvt [arg...]
353
354Creates a new terminal, very similar as if you had started it with
355C<system $binfile, arg...>. Croaks (and probably outputs an error message)
356if the new instance couldn't be created. Returns C<undef> if the new
357instance didn't initialise perl, and the terminal object otherwise. The
358C<init> and C<start> hooks will be called during the call.
359
360=item urxvt::fatal $errormessage
361
362Fatally aborts execution with the given error message. Avoid at all
363costs! The only time this is acceptable is when the terminal process
364starts up.
365
366=item urxvt::warn $string
367
368Calls C<rxvt_warn> with the given string which should not include a
369newline. The module also overwrites the C<warn> builtin with a function
370that calls this function.
371
372Using this function has the advantage that its output ends up in the
373correct place, e.g. on stderr of the connecting urxvtc client.
374
375=item $is_safe = urxvt::safe
376
377Returns true when it is safe to do potentially unsafe things, such as
378evaluating perl code specified by the user. This is true when urxvt was
379started setuid or setgid.
380
381=item $time = urxvt::NOW
382
383Returns the "current time" (as per the event loop).

397Rendition bitsets contain information about colour, font, font styles and
398similar information for each screen cell.
399
400The following "macros" deal with changes in rendition sets. You should
401never just create a bitset, you should always modify an existing one,
402as they contain important information required for correct operation of
403rxvt-unicode.

407=item $rend = urxvt::DEFAULT_RSTYLE

410being reset. Useful as a base to start when creating renditions.
411
412=item $rend = urxvt::OVERLAY_RSTYLE
413
414Return the rendition mask used for overlays by default.
415
416=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
417
418Return the bit that enabled bold, italic, blink, reverse-video and
419underline, respectively. To enable such a style, just logically OR it into
420the bitset.

422=item $foreground = urxvt::GET_BASEFG $rend

429
430=item $rend = urxvt::SET_BGCOLOR ($rend, $new_colour)

433specified one.
434
435=item $value = urxvt::GET_CUSTOM ($rend)
436
437Return the "custom" value: Every rendition has 5 bits for use by
438extensions. They can be set and changed as you like and are initially
439zero.
440
441=item $rend = urxvt::SET_CUSTOM ($rend, $new_value)
