This is an UNOFFICIAL patch for rn 4.3.
Patches through patch 47 should be applied before applying this patch.
This patch is being emailed to Larry Wall (lwall at jpl-devvax.jpl.nasa.gov)
and is being posted to comp.unix.aux.
This patch was created by Herb Weiner (herbw at wiskit.pdx.com)
and is hereby placed into the public domain.
This patch is provided on an AS IS basis. Use it at your own risk.
This patch contains two completely independent changes (apply either or
both):
1. On A/UX 2.0, if the console window is resized while rn has a read
pending, rn terminates with an error. This is fixed by the change
to final.c. This change is A/UX specific, and is conditionally
compiled only if _AUX_SOURCE is defined. The added line specifies
that rn is to use 4.2 BSD-compatible (safe) signals, and that read,
write, ioctl, and wait calls which are interrupted by a signal will
resume at the point they were interrupted rather than generating an
error.
2. A new switch, -p<number> is added to rn. This change should work
correctly with any implementation of rn, although it has been tested
only with A/UX 2.0. The affected files are rn.1 (the man page),
term.h, term.c, and sw.c. The description from the man page follows:
-p<number> tells rn how many lines to display before pausing for input.
This switch is useful if you are using a terminal or workstation
with a scroll buffer larger than the window size, and you do not want
rn to pause at the end of each screen full of text. For example,
-p100 specifies that 100 lines are to be displayed before pausing
for input. The -p switch works well with the -l switch. If the
-p switch is not specified, the number of lines is a function of
the terminal or window size.
