Subject: Changing the sendmail file 
Organization: (National Institutes of Health, Bethesda, MD)
Distribution: usa
Date: Wed, 30 Dec 1992 21:14:24 GMT

As you can see from the above 'From' line, my posts are getting
reported as coming from the mainframe instead of from my SGI.

I was told by the system operator to pull a new sendmail file called
sendmail-sgi.cf off the mainframe and to use it instead.

Well i tried two things.  Renamed the file /usr/lib/sendmail.cf 
/usr/lib/sendmail.cf.old and renamed the sendmail-sgi.cf to sendmail.cf.

I logged out and then back in. Nothing had changed.

I then did the following reccomended by the sysop:

Logged in as root.
at the prompt typed /usr/lib/sendmail -bz

ps -ef (to get the process number of sendmail (119))

kill 119

/usr/lib/sendmail -bd -q1h
Logged out and in.
Again nothing happened except that sendmail now has a PID of 1126.

should I have been typing sendmail.cf?
I noticed the old sendmail was sendmail -bd -q15m  when  the ps -ef command 
  was used.

What should I be doing here?  i have an Iris 4D25 with 3.3.1.

Please either post or answer to my sig address!

The *smart programmer*?  First of all, tempnam() is *NOT* a system
call on any version of unix I have ever used (although presumably
somebody could make it one if they really wanted to do so), and
second, *smart programmers* read the man pages.  As Dave Anderson
already pointed out (with chapter and verse from the standard),
you aren't allowed to assume anything about errno unless the
function/system call is spec'ed as doing something with it.

Anybody who blindly checks errno is not smart, and just asking
for trouble as underlying implementations change, either across
vendors, or across releases from a single vendor.

No, you are completely wrong.  Please go back and re-read
Dave Anderson's response, or get a copy of the ANSI C standard
and read it (which in this case, by the way, merely formalized
something that has been true since at least V6 Unix).

The program is erroneous as various commentators have already observed.

This is specifically addressed by the ANSI/ISO C standard
(using *errno* here for boldface):

ANSI C X3.159-1989
""4.1.3  Errors.
...

The Value of *errno* is zero at program startup, but is never set to
zero by any library function.  The value of *errno* my be set to
nonzero by a library function call whether or not there is an error,
provided the use of *errno* is not documented in the description of the
function in the standard."

Or see ISO/IEC 9899  7.1.4 for the identical text.

tempnam does not document the use of errno, so it can freely
set errno.

If you really want to run a tight loop on generating a unique filename
then you probably do not want to do a fileopen for each iteration. You
can depend on the internal check in all but the homebrew pseudo UNIXs.
I suppose that you could look at the source for these to verify their
functionality. If I can , I'll try to find some doc for this. I had a
momentary lapse of memory, but I do remember this from the "good old
days".   Of course if this is a feature that is no longer "officially"
supported then one would have to discontinue using it.  )-:

Shouldn't this be "cot(fov/20)", since the fov is given in tenths of degrees?

We are porting a program from a VGX platform to a Crimson/RealityEngine,
and have been finding it difficult to make full use of the 4096-entry
colormap when lrectwrite'ing  8-bit images.

Specifically, we suspect that the call

pixmode( PM_ADD24, 256 );

on the RealityEngine, is the problem.


In fact, any integer offset greater than 0 produces anomalous behavior.

The pixmode manual page claims that "Pixel addition can...
be used to offset the range of a color map image",
and our code  works fine on VGX and Indigo Elan machines.

Any hints or suggestions, posted or mailed, would be appreciated.
Thanks!

RealityEngine allows you to have stereo mode in a window, instead of
having the entire screen be stereo. With a Skywriter, it was hard to
mix stereo and non-stereo applications; the non-stereo ones looked
bad. With RealityEngine, the non-stereo applications look just like

xv-2.21 is in the X11 contrib area on export.lcs.mit.edu (and

use xmkmf). The latest version reads GIF, JPEG, TIFF, PBM and others.

This isn't exactly an answer, but if you have the image tools
installed, you should be able to convert GIF files to various
other formats.  On recent versions of the software, the image
tools are an inst'able package, eoe2.sw.imagetools.

You can use "fromgif" to translate GIF files to SGI RGB files,
and "totiff" to translate SGI RGB files to TIFF:

fromgif file.gif file.rgb
totiff file.rgb file.tiff

You can display SGI RGB files with "ipaste."  I think that
"bgpaste," which will let you display an RGB file as a background,
is also part of the image tools.

XV, as a previous poster mentioned, is also useful for this sort
of thing.

I believe that process blocking occurs only when a GL call is made
to the same GL context after swapbuffers() is called.  Thus a single
process can render and swap multiple windows at the full frame rate,
but will stall if it attempts to render to a window that has been
posted for a swap, but not yet swapped.

So if you get some "undefined function" error you'll know why.
If you want to run your program on non-SGI machines, check the LGL package (like
GL, but in LISP).

If you haven't already, take a look at the Graphics Library Programming Guide.
If you have the Development System on your machine (C compiler, dbx, etc) then
you should have this manual.  It has some pretty nice descriptions of how to
use the GL to do 2D graphics, 3D graphics, lighting, antialiasing, texturing,
and much more (oh boy).
